Want an Azeroth task that will keep you occupied until 60?
Run LBRS until you collect all pieces of the UBRS key (gotta go to Dustwallow Marsh as well ) and get the Note from Commander Whats-his-face to kill Rend to complete the quest for the blue trinket.

Then Run UBRS to kill Rend. If you are running Shaman, then I say good luck to you. I was BARELY able to do it with my 60 Druid + 60 shaman group, as the dragonkin in the Rend event are very Magic Resistant. I used the Shaman to kill the Elite Humanoids and did most of the Dragonkin killing with my druid. If you take too long, the next wave will move right in on you.

This will keep you occupied, and you will get a pretty nice trinket to use for a few levels, even longer if you are using the Tank trinket.
