I've been away from WoW for ages, I was a day 1 vanilla player and had some great times with RL friends in 5 mans and the sort (never really made it up to raiding), but we all eventually moved on to other things.
I tried TBC briefly, I tried Wrath briefly.. never made it terribly far in either. I suspect because I didn't take the time to find a mature casual guild and I no longer know anyone in RL who plays.
I realize the basic formula hasn't changed (and is the same for all mmos; chase the virtual carrot), but that said Cata looks like it could add some new fun and exploration _IF_ I put in the time to find good people to play with.
At any rate my main question is; these days I work full time and I'm a full time student, how viable is it to get by on say 5-15 hours a week?
