I would also recommend you add in the Sunken Temple at level 45. All you have to do is the top portion, leave boostees at entrance, have tank run around (one circle) and gather all the dragonkins, kill them back at the entrance, profit. If you want to do the trolls, you can too, not too far of a run. I do this circle, kill trolls, and the five dragons. FYI, if you want leathers, this is the place to get it, leveling skinning and the leathers...forgot what kind of leather for level 50 mobs...
