Nope. When I'm not working I want to do what I want and when I want, not at someone elses schedule, and I don't like having to disappoint a group of people just because I didn't show up for a night.
I would like less levels though, and I wish they would have stuck to the GW1 design for this. Very few zones between lvl 1-19 with the majority of the content being lvl 20.
