IMO Hunters do not work at all in a dungeon grinding group due to the deadzone. I gave up on mine around 20 or so. Fun to play solo though.

Unless you want to main a warrior at 60, I would pick another tank since warriors don't really do anything in a farming group. For example, a pally tank would be much more valuable since you have a second rez and they can do aoe damage so will actually contribute to farming. I ran with a warrior since raiding as fury dps is awesome.

On the horde side, a lock doesn't really give you anything. On alliance side, as someone pointed out, SM would suck without summons. Horde has Brill to use as a base.

Overall, horde is much easier to level a 5 man than alliance due to SM and Gor'shak farming.

I am not sure why chinese bot farmers go with a druid for their tank. Anybody know?
