DKs are currently extremely powerful, quite possibly OP compared to most other classes. I played one in beta and have one I've been playing one live as well. Very fun class, IMO.

I personally love the mechanics. To do really well you have to be on top of your runes and rune power rotations (no AFK killing on this class). Macro rotations will be harder since misses for Icy Touch or Plague Strike will mess things up.

What did you want to know about the class? Just general fun, or multiboxing specific questions/viability?
