I'd be for an auto "pick me the fastest line" option. Like "I don't care where, just get me in". Rather than me having to pick a server I think isn't that populated, find out the queue is long and have to back out and go back in all hoping there are no errors or other issues due to that.

Honestly this issue is standard for all major releases and at least the servers are not exploding like other mmorpgs have often done, so we're doing pretty well comparatively at least... but... I'd be all for even more options to be "it just works"™.
