Mito Requiem's issues with 4.0 SMN

The problems I currently find with 4.0 Summoner.

-I hate feeling locked out of job mechanics. I am unable to use aetherflow during DwT now and I am also unable to go into DwT during Summon Bahamut
-Bahamut following me around like a lost child is annoying especially and it kinda promotes me to be as stationary as possible when he is out. You need to be still in order for Bahamut to cast and sometimes you can get into situations where if you HAVE to move and you hit Ahk Morn he just won't cast it(or do an auto). I'm not really a fan of that because SMN has always been about mobility and you could argue that DwT kinda promotes you to be stationary but using Ruin II in DwT isn't that big of a loss compared to losing Bahamut casts.

-I'm not really a fan of how DoTs are and I miss the 3rd DoT, Bio III and Miasma III being on the same timer is really awkward especially since Summoner doesn't have anything like iron jaws.

-The new priority system is kinda of awkward and sorta makes the job feel clunky at least for me anyways. You use Aether on CD(When you don't have any stacks or Dreadwyrm aether) > You want to always Rouse 60s before Aetherflow > You always want to use Bahamut 40s before Aetherflow > and you want to use DwT 20s before Aether and it repeats back to using Aether on CD. I've practiced a ton of SMN recently and I'm starting to get used to it but I feel like it's something SMNs shouldn't have to get used to.

-Devotion being not only single target but the target that is closest to your egi is the worst, There are a ton of situations where my Healer would just get the buff. I would like the buff to hit the whole party like I think it did in media tour, or let me choose the target.

-This is moreso for Solo play but if they're gonna remove sustain I think our pets should be able to regen in battle, unlikely but figure I mention it.

-Tri-Bind Can the potency get buffed to 80? pls it's so useless
