I also used to do a trapsin, pretty awesome, but never really used her much. Used to play as Paladin Cleric, pure healer, 20 in holybolt and such. Sorcs though, i find it always better to go two builds, like a Ice/Lightning, which was what i was, because of the threat of going only one build, yes awesome for pvp, but useless if you ran up against a monster which was immune to it.
