Having not played a warrior at all but after tanking coil with a warrior co tank I do find even though he has better gear than me he gets hit like a semi

I think to make warriors scale a bit better they need a buff on their self heals this may sound kind of death knightish from wow but the self healing they do should be increased based upon how much damage they took in the past 5 or so seconds. And any over healing they do should be translated into a shield. Since warriors seem to be about spilling blood I would call it blood shield. Then give them a trait that when they use blood bath they also gain a shield along with the healing they did. This would make blood bath a useful skill. Finally I think they should get a parry buff ability since they are about parrying.

I think these buffs would bring the warrior more in line with plds while keeping true to the warriors form of being berserk yet calculating masters of the battle field.
