Granted, fire skills are very painful for anyone (or anything) who wants to mess with a sorcress who has them. But, have you ever seen a blizzard sorc with max synergies? My friend Jesse, he's VERY strong, (lvl 95 barb, can smoke just about anything with throw weaps, and hes not a throw barb...) but, he died in one hit from a blizzard sorc's spell. The amount of dmg needed to kill him.... would be crazy.
