onyxia is doable with 3 man ( i did it on my resto druid - non-boxing )

Mc is possible if you have enough fire resist gear. some of the bosses are just going to be impossible though

bwl i doubt it. its gonna be hell trying to manage the orb and run around killing things.

naxx - well its moving so good luck with that one......

zg - possible - some micromanagement involved
