Necromancers

I played through the entire campaign as a sorcerer. Love the sorcerer. Didn't touch the other characters. Now I'm trying the others out. The barbarian isn't wowing me. But the necromancer is so much fun. I especially like the exploding corpses skill and the domino effect when the monsters keep advancing into already dead ones. I didn't think I would like necromancers, but they may be my next playthrough or the Season 1 character.
