My level 57 priest appears in LBRS for the first time with a level 60 Death Knight. This DK was one of the don't-stop-pulling-until-someone-dies variety. While I'm picking up the quests, he's already pulled a couple of groups. I pop a renew on him and a couple of them run right towards me. I'm not sure if it's this DK's tanking style or what, but for the entire instance I was fighting heal aggro. It didn't help that the tank's pulls usually ended up getting every group in the current room. It was close a couple of times, but I was able to keep everyone alive. It was a good change from the never ending Blackrock Depths runs.
During the Urok Dooomhowl event, where waves of ogres appear, I found that staying right on top of the tank was the best approach. The tank would eventually get control of them, and binding heal kept me alive until then.
Body and Soul lets me drink and then quickly catch up to the group. I ventured way out to the AV entrance in horde control Hillsbrad to pick up some manna biscuits which helps a lot for restoring mana quicky. It's crazy that alliance has no flight points in this zone anymore. It could be that when Cataclysm goes live and Gilneas is populated that some things will change in these zones.
