To anyone who has played the game, i'm on the fence on choosing a Necro or Demonoligist...

Necro summons demons to do his bidding, and uses ice spells from what i can tell...
Demonoligist gets one pet and seems to have a wider range of spells from what i'm reading...

Anyone played either of these classes and can give me a little heads up? i'm at work right now and the game is sitting at home and i can't play it yet so i'm just trying to do a little research to save some time.
