I got a wild hair last night and decided to take my baby shaman to Mount Hyjal. She was 77, so I levelled her to 78, which I had heard was the level that you could go to Hyjal or Vashj’ir at. And then discovered that I was labouring under a grave misconception…it is definitely 80 before you can take any of the new quests.
I just don’t know if I can do two more levels in areas that I have spent so much time in. Hmmmph!
