Team 1:

Type: 5-Boxing
Class Mix:4 Elemental Shamans and a Prot Pali
Focus: PVE
PVE Progression: only level 7 so far :P
PVP Progression:
Usability of this Mix: Seems fine so far, easy to assist the pali and 1shot stuff at level 7, I'll see how it goes as I get more spells etc


Team 2:

Type: 5-Boxing
Class Mix: Prot warrior, 2 mages, 1 holy priest, 1 lock (I'm starting with 3 mages, one of these will stop at 39 where a lock I already have replaces him)
Focus: PVE/possible pvp
PVE Progression: just starting out
PVP Progression:
Usability of this Mix: Will be trickier than the other group due to class variety but doable I think. I've played mage to 60, lock to 70, priest to 70, tank/warrior to 67 so I think I can work it out

I'm also tempted to get a group of 4locks and 1 priest just to PvP, so SICK of all the "nerf locks" whining on the forums (my main is a lock for PvE) that I'd really enjoy slaughtering the whiney little turds all day
