Ok, got into multi boxing yesterday on classic. Trying 3 mages. I have 3 dumb questions for the hive mind.

1. What are strategies for handling spells like frost nova so that only one person casts at a time? Do you use castsequence? Does that get screwed up with cold snap?

2. Do people spec all their mages ice for AoE? Or do they put some as fire or arcane at low levels?

3. Ok, I know the answer has something to do with interact, but I can't get it to work. How do you get everyone to face the target so they'll cast? It's killing me, lol. Literally. Is there a macro command I can put in front of spells to get people to face it?
