If you are having problems with zons with that gear and build, then your problem is that you're too slow.
Use more faster run/walk small charms, and ditch the corruption heart for a Cat's Eye (IAS for zerk, 30% frw, and 25 dex for blocking makes up for the dex lost from cheart, and then some)

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