I walked away in Cata came back briefly at 4.2 hope firelands would be all a nice change of pace (it was not), and MOP seems to be same junk. At least this time i am not coming gave away all my herbs, ore, cloth, and gold to one friend that still plays.
Also it is just not me out of my original guild of 20 RL friends and 30 friends we meet playing WOW, i was the last one to hang up.
