I will gladly take chaos knight. In true tank fassion i would use life tap and even being hosed by diablo wont kill u if you zeal using life tap. Im gonna rant on life tap cause i love this skill. 50% life leech is insane. Plus, correct me if im wrong here, i think it lets u bypass leech penalties allowing u to always leech 50%. Its the second best leech in the game, after hunger, but you dont take a damage penalty. Its crazy good. With passion its even better cause of the really fast zeal attack. So on my "chaos knight" (thanks thrandir) even if monsters bypass your bone armor and max block they wouldnt be able to hurt u anyways. ahhhh so good. Of course blind and terror are problems, but in crowds i generally use decrepify anyways unless against a lot of casters and or bosses.
