Only 2 cents I have is that I would spec the mage Arcane and the Hunter BM, I have both on my teams and Arcane does massive damage and survival hunters have a lot of procs to watch which ultimately can lower your dps. my order of preference for the hunter in a multibox situation would be BM, MM and then survival. I have been playing my hunter as MM and currently looking at BM which seems to give better sustained dps.
