Sorcs will own all, if you know how to tp, you can beat all meele chars, including FOH pallies, you can beat all amas about 10-50% of the time. Assasins and such might pose somewhat of a threat, I myself didn't duel gosu long enough to see many good avs duels.

Sorc is the over all best, only random arrows, or i guess dragonflight could beat them, or another sorc with lots of cold res.
