While the hotfix patch notes aren't expansive (all seven fixes are listed below), they do address some of the worst bugs pertaining to the queue system and getting on a certain realm. I know I've seen about all of these problems except the one regarding reporting spam, as I haven't had to do that yet. It seems like they've fixed all their queue problems, which should make the rest of the weekend go much smoother!
Carbine's got another hotfix coming tonight (Build 6682), it's not a big patch by any means but it does cover some pretty important bugs, like the constant crashing that some users reported having. The servers will be shutting down May 16th at 12:30AM PDT / 3:30AM EDT / 8:30AM UTC to apply the hotfix, the servers are expected to be down for approximately one hour.
