Honestly wrath needs to require less stacking considering from beginning to end its 20 seconds to get to innerbeast which even popping your offensives isn't an amazing heal (its nice but you're pretty much losing that health in the next 2 hits or boss ability). As a tank thats supposed to be about self healing we should get cds that feel as powerful as a paladins mitigations cds, but built around our health recovery through dmg mechanics.
