I really want something that interacts with our beast gauge. Something like a shout that I mentioned in one of my threads. The skill would reduce the Warrior's current beast gauge in half, and give an effect based on how much beast gauge you lost, and which stance you're in. What the buffs should do though, I still haven't decided yet.

In my thread, I proposed the effect under Deliverance be an extra damage bonus, but someone pointed out that would be too strong. So we'd have to come up with something else. I think some extra critical rate wouldn't be all that bad. Something in between 5-10% (varied based on how many points you lost).

As for the Defiance effect, it could be what OP said - increased max HP, or maybe even increased healing for the next couple of seconds.
