The game is great. I stopped playing because I was sick of having to cater to guilds for decent groups on the final raids. That, and everyone was pretty much a douche (was on 2nd best guild on server; enormous pressure usually). I just noticed I enjoyed my "me" time in the game a lot more than the terrible, terrible moments in a raid. I played a lot, about 7-8 hours a day, had little sleep, and while I can't say I was a shining beacon of good grades and social relationships (never have been anyways), they didn't suffer much. So I went back to console gaming, quicker and a lot less group-dependant (unless you count Team DMs in certain games, but you'll never get much teamwork out of it anyways).
I'll prolly get back to the game when the next expasion arrives, but I'm not so sure I'll continue playing after I get my favorite characters (DK, Rogue, Mage and the next hero class!) to level 90.
