Furia's wrath bar decays way too slowly. It's pretty much always full and there's never an issue getting it there if you died and it decayed a little.

This makes her a little too good at dealing damage. I suggest the decay rate is increased so that it is actually a bit of a challenge to maintain full wrath bar and thus full damage potential. As it stands she might as well not have the bar and just have her firerate be what it is at max.
