The fact that the Sorceress has a skill that automatically gives her Mana after each kill is just sex.
And ZOMG - putting points in Energy actually makes sense now!
Not really, imo, sorc is the worst class now. They don't have any good mass killing spells unlike in D2 original. By the time you get high level MP is practically useless, and with Arcane Torren, sorcs don't WANT mp.
