I've been having this same issue all day. There's no option to return to your home world from the login screen, you have to do it from an aetheryte in game. So you have to wait in the 4000+ queue to login to the (wrong) world, and then wait 4+ hours in the queue to travel back to your home world... The worst part being that you can't do anything while you're in the queue, including traveling to another map. So you're stuck in the main city of a server that isn't yours. And you can't even afk to wait out the timer, because then the game will d/c you for inactivity. This system is seriously messed up. The only way to MAYBE get in is if you log in at an obscenely awkward time, like 4am, to try and queue up while hopefully everyone is sleeping.
