I don't know how complicated it would be to implement, but players who exit the game without a successful logoff should jump to the front of the queue. DirectX errors, 90ks, whatever the reason, it's terrible to leave a group waiting through a 5k queue. Let's not pretend it's rare, this game can be a completely buggy mess even though I love it. Sound crashes, DX, etc. Especially with raiding coming up soon. There needs to be a retention/recognition of that logoff transaction to let people back in if they try.
PS. I don't post here and won't check the comments, just hope some SE employee passes along some ideas.
