Wow, I don't even care if doing this isn't viable in hell mode, but I have been using this along with the rest of my build for Nightmare mode (almost through act 4 now). Using this whenever its off cooldown decimates things in supreme hulklike fashion so freaking hard, I can't get enough of it. Now I just need to level up so I can get the rune that lets me stay in WotB mode longer by gaining fury and I am set.
