People will just go to an inn room and run into a wall or "follow" a moving NPC. This method would probably only open up a few spots and those would be taken quickly. I don't see it as being the right way to handle this, if we were going to stop idlers we would have to kick EVERYONE off the servers every few hours, and I don't think anyone would like that much..

Fix the machines and software and what have you..afk timer is useless IMO.
