Defiance is fine as is. Its the wrath stacking that kills it. I think all (if not most) of the skills when under defiance should produce wrath of some kind. i.e Overpower produce's 0.5 stacks meaning spamming OP 4 times would give you two stacks.

There should also be a rotation bonus for successful execution. That way you can build 5 stacks in two rotations rather than 2.5.

i.e Heavy Swing > Skull Sunder (add one stack) > Butcher Block (add one stack) > (one stack bonus for next Heavy Swing) > Heavy Swing (add one stack) > etc.

And I do not agree with giving wars more def cd's cause the point of a war is to "manually" mitigate the damage. Meaning "you" the "player" must mitigate it yourself and that is the true nature of how wars should be treated. Not as a passive buff like shield oath. Also fix Storm's Path because the tp cost far outweighs its utility and the measly 50% of hp absorbed (roughly 70-120 hp) is not worth the 10% slash debuff from Storm's eye imo.
