I'm planning on 3 teams, maybe 4. My main account has 2 lvl 70 tanks, Very geared warrior and decent pally, so I won't include tanks while leveling.

So I've got so far - 5 shaman
3xMage - holy Preist
3xLock - SPreist interchangeable with the holy priest for endgame instances.
For the 4th team, I was thinking all hunters, 5x druids for a bear tank 3 moonkin and a tree, or some other combination I haven't thought of yet.

Since I had linking problems in setup, I'll be able to grant 2 instant lvl 60's for every 2 teams to get to 60 as well as topping off several alts I was working on on account #1. so for the first 2, I was thinking of Holy pally and Rogue. Then from there, insta leveling 2 other classes whose specs could be fun to play at 80, like 2 more warriors, so I could have one just fury, one just arms. I'll have tanks and healers on 2 accounts, dps on the other 3, with a few mixes and matches so I can change the groups to suit certain encounters.

I'll have a ton of solo classes to play, a ton of options at the login screen, and it seems as if RAF has finally given me a reason to never go outside again. The mages would actually seem to be the most instance friendly. High dps, reliable cc, and next to no maintanance with free water. But then again, shaman are getting hex, so even the mages niche of 3 sheeps is up for grabs.
