OK guys, I got Diablo III on sale for $20. Impulse buy, feeling the hype for the expansion, etc. I don't know what class to play, what my basic strategy is, nothing. Probably won't play past Act I of Hell if my D2 experience is any indication. Hopefully they won't wipe my doods when the expansion comes.
I like tanking, auras, and summons. Prefer mage or warrior classes to DPS or archer classes. Tell me what class I should go for. Deciding between Barbarian, Witch Doctor, and Wizard.
