Punishing divas who jump ship before a dungeon even begins.

I enjoy DD, I also enjoy AV. Funnily enough, I like them as both tank and healer.

With respect to healing AV, you are in the minority. That is all I will say. Tanking AV is whatever, there's nothing particularly difficult for a tank in there. Really good XP for that stretch between 45~50 though. I think it actually gives more XP than Dusk Vigil
