I still play my 60 hunter every now and then, but there is no one to play with so it gets boring very quickly.
During the first weeks of August, I randomly fell upon a group of 64 twinks farming exp-on BGs, I tagged along and added them up on btag to join in. That was the last time I did anything involving more than 3 60s in the same group.
At the start of the summer, Moon Guard had a 60 raiding guild going on which had weekly raids, but I was barely ever on because of work conflicting with raid schedules so I cant really add anything more on that. The guild is dead now.
Apart from going on the Noob-hunt "lonewolf-style" in Hellfire Pen, there is pretty much nothing else to do PvP-wise...
And ever since I have gotten BiS (2 years ago), I have stopped doing my weekly raids. So I dont even do those any more!
