Hi All,
I've noticed that once you get into your respective server (you need to queue the first time) and log out back out to the character selection screen, you do not get thrown back into the queue; no big deal there. However if you like me are able to leave your computer on overnight this means no queue when you want to carry on playing!
I've left my PC logged into the character select screen for several hours and haven't had to re-queue...
Not really an exploit but I've been using it given the horrendous server log in times currently.
