Sorry for a late answer, bein out whole day and taking caring of my bees (I'm a beekeeper ).

Yeah, this multibox idea seems so fuckin much fun, a new experience to WoW.

So atm I thought it would be a lot easier for me to start like 4 classes (with DPS/Tank class) and 1 healer class such as

4x warriors, 1 disc priest/pala
4x priest (split up between disc and shadow) 1x warrior (tank)
5x shamans (not sure how they perform in MoP, any ideas??)

any other suggestions that can be made for a newbie? Would love if they could deal some bigass DPS too, but I will give some serious time to gear everyone up as best I can

Have a great night and Box ON!
