Im hesitant to use grizzly rage because either way i lose the ability to use most of my skills. Im running claw, pulverize, bulwark, hurricane, and creeper.
I dont have TR or vasilys either so i feel handicapped when i use griz rage. Ive been liking petrify though. The crit damage and the 25 spirit per kill works well with pulverize.
I do use the unconstrained beast heart though. That thing procs all the time too.
