Yeah, I know. It would just be an easy fix that would open up a few extra comps without breaking balance. It just kinda sucks that right now you pretty much gotta go with WAR+DRK or WAR+PLD+MNK*. One of those is a three man team and WAR+DRK is still better than it for raid damage because of Reprisal. I don't think it's too unreasonable to want pretty much any comp of 2 tank/2 healer/1 caster/1 ranger/2 melee to be viable as long as they're all different jobs.
As for Deployment Tactics, I think DV/Mantra/Succor should be around +500 HP over Conva/Defiance/Deploy. I think MNK Mantra on the war/sch team would equalize them - my numbers could be off, though, since I'm just going from some week old logs and napkin math. Anyway, I think that the general power of Scholar and its shields is what has made raid damage creep up so high, and synergy with healing buffs is part of that. It's not even really a warrior thing, the extra Defiance buff just pushes it farther.
Maybe I'm just still triggered from seeing Cascade one shot my damage dealers when I was still running paladin for living liquid. It probably won't matter in 3.4 since it'll be easier than Gordias/Midas (I hope).
*I know you don't have to bring a monk since I didn't, but I really wish I had.
Also sorry to post this stuff in a warrior future thread. I don't think warriors have much to be worried about though. It'll just be that the rising tide (of level cap increase) won't raise their boat as much as the others.
