he doesn't want to duel sorc because his life/resists are so low he'd die in 1 ts.
Looking at that build, even if he stood still he would rape any but the most hacked melee char on east. My friend's ama with that build does 7.2k guided, with 100% pierce, 8frame attack and knockback, if I get hit once im stun/block locked until I die.

/w *thesuck for duels.
I use only legit but will be happy to take anyone on 1v1 in a friendly duel =)
