Should be no reason for this. I could see this being implemented for a F2P game (which, even then, they don't even do), but why auto-log players to alleviate something that should be working? Also, this isn't the fault of players just staying logged on. There are not an extremely large amount of players on these servers by MMO standards anyway. Doesn't matter if they are idle or active. It's their problem, not ours.
