Sacred Haven of Debauchery

by the way, has anyone played as a Necromancer?

My brother played as one. I still remember how he came to Diablo with an army of skeletons and other abominations. The Red Demon took them all out with a single blow.

I myself played through it many times. Mostly as Paladins, though.
Paladins:
83, 60+, 50+ and lower.
The others didn't even reach level 40.

P.S. It would be quite difficult to play as a Sorceress on the hardest difficulty, because practically every NPC has resistance.
