I'm leaning towards 6x Warlocks, 1x Shadow Priest, and 3x Resto Druids.
I keep bouncing back and forth to 7x Warlocks or 6x with the Priest.
I like the extra buff and Mass Dispel.

I visited the CDC website, to get all their names.
It should be a fun team.
Nice team Ualaa, I have been toying with a similar team except 5 locks, 1 shadow/dis priest, 3 resto druids, and a mage for the 5% spell crit. Also I wouldn't have to level another lock. Not really sure the 5% spell crit helps this team for normal BG's though.
