We have a lil mbox guild on Khaz'goroth and currently there is 4 5x boxers. We each have our own PVE heroic farming teams:

Boxer 1: Main Crew: Prot Pally, 3 ele shams and 1 resto sham. (dual specced ele)
LVL 80 alts: 2 Mage+ 4 warlocks.

Boxer 2: Main Crew: Prot Pally, 2 ele shamns, resto sham (dual specced ele) and destro lock.
LVL 80 alts: Priest, 4 warlocks.

Boxer 3: Main Crew: Prot Pally, 3 ele shams and 1 resto sham.

Boxer 4: Main Crew: Prot Pally, 2 ele shams and 1 resto druid, 1 hunter.

So was just wondering for some feeback/suggestions from the raiding mbox guilds, for a good place to start and learn some mbox raiding
