I just found this out a few minutes ago but i noticed that someone else had posted something similar. How I discovered how to skip the queue is different and much easier though. Follow these steps and hopefully it should work:
1. Log into any server that has no queue.
2. Click Change Realm and select the server you'd like to move to without waiting in queue.
3. Once the message appears that states how many people are in queue, hit change realm, then cancel.
4. Press back to go to the WoW login screen.
5. Enter your account info again and you'll be right at the character selection screen, no queue!
I have tried this several times now to make sure, but post if you get it working!
Edit: Doesn't work anymore apparently, just tried and it didn't work. It was nice while it lasted!
And thank you for the rep
