if you had to make 2 x5 groups with all classes, how would you do it?

I am currently out until MOP but i was running

Feral (tank), Disc heals, ele, arcane, survival

Prot Pally, Resto Druid, Enh Sham, Fury Warrior, Frost DK

I had fun with it. Also when the groups came together i could move this around to make it more melee centric or ranged.
