It sounds ok but quite few chars can tank the poison and multi shot, for example paladins and barbarias. Curses are bm so you'll be going up against 75% resi and on some rare occasion you'll find a smiter with death set gloves, he'll be able to take you out 1v2.

Edit: I still like my foh/mage + trapper combo although stacked resi + tg > me.
