Sorry I just seriously doubt that a sorc could get through hell ancients...at least one full immune and unless you had a godly merc...and any melee build may take a while to get through hell could easily do it, gotta be good crowd controllers but any 1 v 1 boss should be quite easy
I can guarantee you that a sorc can beat hell on its own. I've done it, and that was without any gear or outside help at all.
