I've read the general thread on donations and premium accounts. It says any player that has premium account has a permanent queue skipping on all realms. Does that apply to people without characters on other realms than Outland ?
I just donated 10$ and got the premium rank. I am in the queue since before I donated,and I'm unsure if I should relog and check if I actually skip the queue,kind of risky.
You should be able to log in free once you get premium status. It works permanently for all realms except Lordaeron, where it lasts for one month if I'm not mistaken.
