Well, you can't see movement (or so I seem to recall), so you're going to need a good head and presence of mind. Abuse your healers, and give anyone who has any proficiency with staves one. That means that Mic's not going to be so much a ranged fighter as she is in the other difficulties, though it's a good idea to give her some practice in that for the endgame regardless. Ummm.... Oh, yeah, Abuse Kurthnaga in 4-3 with Paragon/Dragonfoe. I think that's all that I can tell you right now.
