The story I got furthest into was as a smuggler, but I enjoyed the sith storyline for one of my characters, but I didn't get too far into it.
I enjoyed it so much, because it felt a bit like Mass Effect, and could be enjoyed solo.
I think the last time I played WoW was not long after they released the Panda race and their portion of the map.
Do they still have it set up that you can play as far as level 20 for free?
I think I started a smuggler at some point. Or maybe it was a bounty hunter. Can't quite remember. It's been a few years since I played last time.
I know there's some kind of trial for WoW but I don't know what it entails.
