I was curious as to who else came up with this interpretation after the producer said this.

"I believe that a lot of players are using Inner Beast to self-cure when taking a large amount of damage, but after becoming infuriated with five stacks of Wrath, players receive a 15% curing bonus, so instead of using Inner Beast right after taking heavy damage, I think it would be better to wait for heals from a white mage or scholar."

Considering all Warrior skills take all wrath besides Defiance and Infuriate the current fix is to not use warrior abilities at all? And your telling me the class works as intended?
