with my dk, 3 rets, and a friend healing, we 5maned the Draenei (Exodar) and Tyrande (Darnassus). Each one took about 10-12min, had a few people try to mess with, but was easily handled.

Did not attempt Ironforge or Stormwind. Mostly because, I got in a For the Horde group about 3 days later.

However, I did try something on my Alliance toon. Got a MOTW, a fire res pot/ flash (can't remember). My thought was, to pull the Ironforge guy down in the bottom of the lava. I don't know if that's even possible, but was trying to figure out how much fire damage I would be taking, and if we could heal through that and the boss. Then, kinda scrapped it, since you pretty much need 2 tanks for the dude, since he has an agro wipe. Not an issue if you have another tank, but I didn't.

Stormwind, seems like most of the runs I have been on, he gets pulled into a side room.
