Have you tried Neverwinter? It's a lot of fun and done very well in my opinion, plus it's based on D&D so that gives it bonus cool points. It doesn't have a ton of character customization as far as appearance goes, but there are plenty of character classes to choose from and that changes both the look of your character and has a drastic impact on how you'll play and experience the game. I've been playing it on and off with friends for a few weeks now, and that says a lot considering I've never been big on MMOs in the past. Definitely try it out if you haven't!
