Dte, have you considered either an Artie or a Monk, or even a Druid? I know we currently have a few druids, but they are a solid support class. I really enjoy the AA; it's versatile and good for solo runs. I plan to keep mine for the epics.

Sherwin, I'd keep your Sorc through the epics, at least for a short while though you'd likely find them easier with a second lifer. I TR'd my Sorc into my AA, but there are other possibilities such as a Wizzie, or even another Sorc. One other thing to consider with a TR is whether or not to try a splash build. I have a couple and they seem to work well for me.
