NOPE.

If you're not playing, let other people to play. They ALL pay for this, not you only. If you get logged off, then log in and wait in the queue if the world is full. This function has been implemented in a lot of MMOs... so, if you're one of those perma-AFKers, then I'm glad your party is over.

Also, if there're less people connected (You know, putting the AFKers offline), the servers won't be overloaded and there will be less lag issues.
