bk not good because if your a barb or melee or something u are ognna use raven frost probably and some higher life leech...... and if you are a mana guy u should use soj anyways, because bk only adds like 50 life, not much
Life leech doesn't work in duels... if you haven't noticed. And who actually plays the game now? It's all act1 for about an hour or two, get rushed, baal, get rushed, baal more, duel, baal, duel, new char. Rinse & repeat.
