I used to play but gave it up. I wasn't very social in it and kept drifting from guild to guild not making many friends despite playing it a lot I never did much/any end game raiding, I went to Kara a few times but no MC or anything, I kept changing my characters too much and went off instances when people were horrible to me, but I gave instances another go in TBC. I did once find a small friendly guild but it broke up after a few weeks so we couldn't go to Kara but I stayed with it because there were some nice people left.
Stupid thing is since I stopped playing Ive been more depressed and OCD than when I was playing although I didn't like being addicted to it, which I probably was at least it gave me something to do, now I'm bored a lot!
