Option a:

I talked to a Fencer ingame earlier who is Barb3, and Frenzy might be good but I have my doubts. You can only build frenzy stacks with auto attack, which is a waste of time. Warcry is decent in the right situations.


Option b:
Sword3-Pelt2-Fencer3

It's really just swashbuckling. This is a wonderful skill in almost all of PVE - dungeons and grinding. It is only irrelevant in MVP'ing which is what you are building your character for.

If you want to be true MVP champ, peltasta is not necessary. If you want a character that is loved in dungeons (much of the end-game content is dungeoning, you may find that you fill 2 slots in 1 just by having pelt vs not having pelt) and grinding, pelt 2 is probably better than Barb.

Note that 1 rank in pelt is good for level 1 guardian due to the evasion attribute.

Option c:
Sword3-Pelt1-Corsair-Fencer3

You already know this build too. It's another more generalist thing, it doesn't directly contribute to your ability to MVP. Jolly Roger is good, and having BOTH jolly roger and swashbuckling is pretty cool for your party. Iron Hook is top 3 cc in the game, and this is a game with crazy-ass CC. But in PVE CC isn't as important.

But the main benefit of this compared to pelt2 is probably the costume.

Option d:
Sword3-Pelt1-Barb1-Fencer3

This is like above, but the utility of CC/Jolly Roger is replaced with "a little more raw damage". Really the only relevant thing is Cleave, because it has Crit rate increase.
