MoP is the expansion that has made me quit WoW. I've taken breaks before, but yeah, I'm done with it now. I will always look back with fond memories of Burning Crusade and parts of Lich King.
GW2... meh. I played it, the soloing was ok, but I basically just felt like the grouping was completely devoid of any control. Felt like each person was basically just soloing, and his friends happened to just be in the same spot as him. I don't play MMOs to Solo, so I'm done with that too.
Meanwhile, the Planetside 2 Beta has been steaksauce, so that's still looking good.
And then TOR's going F2P, which might signal the time to go check out what's new since I shelved that a while back. Playing a trooper was awesome.
