What's the visual distinction beween a Bloody Choppa and a Big Choppa? Honestly, it seems unnecessary; just give the Big Choppa rending for 10 points or so and it would be fine.

Bubblechukka should have something to represent trapping targets in the bubble. Binning at least.

Grotzooka is a pain to use with the current rules, especially when you have a load of them in a kan mob. Would be better as just a shitload of dice, shorter range and less S than a big shoota, but more shots and maybe shred.

Kustom Mega Slugga is not worth 10 points.

Supa Shoota is annoyingly weak against enemy fliers. I'd rather it be like an autocannon.

Having different rules for the Deathstorm Mega Shoota and the Supa-Gatler seems unnecessary. They both represent more or less the same kind of gun.

Having Buzzsaws and Killsaws be different also seems pointless. Let Deffkoptas just take killsaws.

Smasha Gun should have the Graviton rule, it's a grav weapon.

Skorcha Missiles are a bit crap, especially for 10 points each. Need to be 5 points at most.

Grot prods being dependent on user S seems wrong. Also, I always thought they should have Haywire.

Zzap Guns are rather pointless when KMK exist. Change them into something more interesting, like haywire.

Making Bomb Squigs a blast weapon seems more in keeping with the concept.

Gitfinda adding a straight +1 BS seems maybe a little too good for ork tech. Possible alternatives might be +1 BS against targets within 12", cancel any bonus to cover saves (from Stealth, Shrouded, etc), reduce cover saves by 1 or make maximum cover save 5+ (or, for humerously unreliable orkiness, have cover save always be 5+ even without any cover in the way).

Meks Tools seem too reliable compared to other races repair units. When I was daydreaming of a homebrew ork codex, what I came up with was this:

1-2: Vehicle recovers a hull point if it is missing any, otherwise loses a hull point.
3-4: If vehicle has suffered a weapon destroyed result, one weapon is restored, otherwise, one weapon is destroyed.
5-6: If vehicle is immobilised, it is no longer immobilised, otherwise it becomes immobilised.

Which might be a bit complicated, but seems more fun.

Big Meks seem like they should get two repair rolls or something to represent their superior skills (and higher points cost).

Cybork Body should probably stay as FNP. Bionics are pretty much all done using that rule now. Just change it to +1 to FNP rolls or FNP(6+) if they dont have FNP.

Mega Armour giving slow and purposeful creates weird rules glitches. Better to just say they can't run, etc.

Red Paint Job effects seem excessive and not all games use the DFTS rules. I'd be tempted to just fucking well remove it from the game and say how you paint your models has no in-game effect. If you are going to include it, maybe have it do something to walkers too?

The current Deff Rolla rules are shit, but I don't think going back to the ridiculous old ones helps much. Not sure what to suggest though.

Having Grabbin Klaw rules that are totally different to the Wreckin Ball ones seems weird. Just making them both into very short-ranged weapons would probably be easier.

Stikkbomb Chukka wording is a bit awkward. Maybe have a seperate bit of wargear using a different name for walkers with grenades? Also, almost all units already have stikkbombs, so they are a bit pointless unless they offer something extra. Maybe having them function as smoke launchers would be better?

Tellyport Device seems like it would be very awkward if the two models have different base sizes.

The extra turbo-boost move on Gazbag's Blitzbike is rather pointless, as you would almost certainlly want to keep the character in a unit of normal bikes. Maybe allow shooting while turbo-boosting instead?

Personally, I'd rather keep the slightly crap ork psyker powers and give weirdboys a bonus to harness warp charges for them. That way you can keep using the ork cards.

The formations seem to have a lot or warbosses. Surely it is more thematic to only have one warboss (big mek, etc) in each detachment?

Requiring only choppa boyz in the Green Tide is awkward. Pretty much everyone running one is going to want to use all their models.

Seems odd that some clan formations require a HQ unit and others don't.

Traditionally (in second edition, at least), Bad Moons have weirdboys, Deathskulls have painboys (and runtherd and the unique ability to take two oddboyz per boyz mob in Freebootaz), Snakebites have runtherds (and painboys in Ere We Go and their weirdboys were noted as being more powerful, but no more common than in other clans), Evil Suns have meks (and the option of an extra nob per boyz mob in FB), Goffs have more nobs. Blood Axes didn't get any special oddboys in 2nd edition (they got meks in EWG).

Stormboyz were a unique Goff unit at one point (while Snakebites had boar boyz, Deff Skulls had lootas, Blood Axes had kommandos, Evil Suns could mount everyone on bikes and Bad Moonz could take more wargear), so you might want to make them a part of the Goff formation. Killa Kans don't seem very Goff at all; proper Goffs wouldn't stand for Grots being given power like that!

Freebootaz don't seem like they should be a core option.

Dread Mob should probably have the option of more models.

Not sure how deep strike is a good Bad Moon bonus. Going with the way some recent formations have done things, I'd suggest giving them all wargear upgrades for free, or at least giving each boyz mob free big shootas and rokkit launchas.

I think Zagstrukk is a Goff, not a Blood Axe, so probably best not to put him in the Blood Axe formation.

Deffskulls special rule seems confusing; why does the warlord target the enemy unit and how long does the effect last for? Not sure if it's a good fit for the clan either. The Ad Mech Holy Requisitioner formation has an 'inhuman avarice' rule which might serve as a basis for an alternative; models get counter-attack and zealot while within 6" of an objective.

If you are including rules for Red Paint Jobs, maybe make them compulsory (and possibly free) for Evil Sunz?

Not sure how the Freebooterz rule is thematic.

Choppa of da Ragnaork seems overpriced.

Might as well throw killsaws into the general melee weapons pool and let mek characters buy them from that. Don't see why a mek couldn't have a claw or big choppa; GW only restricted them to killsaws because that's what's on the model.

Rokkit Pakk as a general-issue item contradicts the old fluff about them being exclusive to stormboyz. Maybe have an artifact rokkit pakk for Goffs or Blood Axes?

Ld 10 on warboss seems excessive and makes bosspoles worthless for him. Also, Waaagh banner is traditionally not carried by the warboss himself.

Big Mek should probably only be Ld 8, but is a bit overpriced.

I'm generally a fan of having a boss and normal version of each oddboy. I'd have called the boss painboy a 'bad dok', in line with the warphead being the freeboota special weirdboy in Freebootaz.

Could maybe have a 'boss' version of the runtherd? Runtmaster? Squigboss?

Warphead having Nest of Vipers as standard seems wrong to me. Zogwort should have his own rules. Also, you seem to have missed Eavy Armour from his wargear but given him a 4+ save anyway. Personally, I'd make it optional.

I think I'd rather have the basic weirdboy with a boy statline. Drop the price way down too.

Mek seems a little expensive, but you are using some good repair rules so maybe OK. Should really be allowed Orky Know-Wats, I think, or cybork body, eavy armour and gitfinda as options at least.

Painboy could use some options. Cybork body at least.

Mad Dok Grotsnik is way overpriced. He's only about as good as a Warboss with a claw plus the painboy FNP. That's 110 points.

Kaptin Badrukk is overpriced. I'd say he's worth maybe 70 points.

Boss Zagstruk seems OK with that AP 3 choppa. Possibly even a little cheap. He's always been let down by how weak stormboyz are, not his rules.

I like Boss Snikrot being in HQ, but he needs a warlord trait, possibly a unique one. His special rules seem a bit too good; he's sneaky for an ork, not one of the sneakiest characters in the universe. Stealth and Acute Senses would be fine. On the other hand, his statline could probably do with being buffed up a bit. Initiative 4 at least. Hard to say if he's really worth the points as you are mostyl paying to get the kommandos where you want them. I'm inclined to say he's a bit overpriced at the moment.

Choppa Boyz are overpriced. They need to be 5 points per model. No need to have the existing weapon choices changed, in my opinion.

Shoota boyz are probably fine at 6 ppm.

Eavy armour on boyz seems only worth 2 points to me.

Grots are probably fine as-is. Could give them scout, I guess.

Tankbustas seem a little overpriced. Would be nice to let them have eavy armour too (although probably charge more than boyz pay). Their nob should probably have a unique list of upgrades rather than choosing from the standard lists.

Nobz seem OK with the free Eavy Armour. I'd only give the Boss Nob Ld 8. Warbikes might be a little cheap for 10 points, but only a little.

Flash Gitz work fine with free Eavy Armour and improved gitfindas, although the option for Cybork Bodies would be nice. Not sure why they would want to swap their snazzguns for anything else and they need a choppa to buy melee weapons, right?

Meganobz are fine.

Kommandos are overpriced. They are worth maybe 8 ppm as is, less if you take away their stealth (I would, but I can see the case for giving them something to distinguish them). Eavy armour probably shouldn't be an option for them.

Mixing Deff Dreads into Killa Kans is just confusing. I'm quite fond of the current Cowardly Grots! rule, but the cost per kan does need bringing down to reflect it; probably about 30-35 ppm. Grot Riggers and Extra Armour on Kans are not worth 10 points each, probably not even 5 points each. Kans should be heavy support in my opinion; nothing piloted by grots deserves to be called elite!

Trukks don't need complicated rules. We've got enough rules for vehicles falling apart as it is. I'd just drop Ramshackle entirely. Probably drop cost to 25 too.

There isn't much to be done with stormboyz except to drop the price. I think 8 ppm doesn't go far enough; I'd say 7 ppm. Wouldn't give them the option of eavy armour or would charge more if I did.

Deffkoptas seem about right. Comparable to Eldar Windriders.

Planes could all do with some more armour (front 11?) and a drop in points (about 20% cheaper, I think).

Warbikers are maybe still a little expensive; they are one of the best units in the current codex, but not really competitive with eldar, etc. Maybe drop them to 16 or 17 ppm?

Warbuggies could maybe be a little cheaper, but 20 points seems slightly too cheap. 22 ppm?

Wartrakks seem like they should be a seperate unit, maybe a 3 point upgrade to a buggy? Not worth 5 points anyway.

Skorcha isn't worth paying points for when you trade a twin-linked weapon to get it. Either make it twin-linked too or make it a free upgrade (my preference is for the latter).

Warbuggies and trakks could have a KMB as a weapon option. The current buggy model seems to have an energy weapon and I believe the classic metal models did too.

Ard Case could be an option for buggies and trakks, since many models people use have enclosed cabs. Maybe a 3 point upgrade? Most upgrades need to be about half the price you have them at to be worth considering for such crappy vehicles.

Big Squiggoth seems a bit weak for it's points cost. Guns are overpriced too.

'Looted Tank' seems like a bad nam for something which might not have the Tank type. Stick with 'looted wagon', I think. Trying to put a bunch of rather different vehicles in one unit entry is probably a mistake.

Mek Gunz either need their weapons rebalancing or a points cost adjustment. Zzapp Guns are not worth 5 points more than Kannons. KMK and Traktor Kannon are probably a little too good for their price, Bubblechukka and Smasha Gun not good enough. Seems like you should be able to take an ork supervisor of some kind too; either a mek or a runtherd.

Battlewagon seems about right. Ard Case is way too expensive though.

Deff Dread is OK, I guess. Maybe still a bit pricey even with the extra attack.

Lootas probably didn't need new rules. They do a job and do it fairly well. Just drop their points to 12 ppm.

Burna Boyz seem to have disappeared?

Ghaz as a MC doesn't really work for me. Give him most of their rules, but keep him as infantry with the extremely bulky rule to avoid issues like him ot being able to get in a battlewagon, questions as to whether he can join units, etc.

Stompa seems basically OK with the points reduction. I would have to mathhammer it vs. imperial knights to see if it works out... would ideally like options for the FW upgrades or at least the old Big Mek stompa.

I'm kind of fond of having the Gorkanaut and Morkanaut as two different units, but the rules you give them seem OK. I might have left them as heavy support.

Garganuan Squiggoth I'm not sure how to price, because I've little I can compare it to. Seems OK at first glance.
