Whether the AFK players are affecting anything or not, SE please consider implementing a timer anyway. Because:

1. People who are having difficulties logging in have a hard time accepting that a world is full when its obvious characters are logged in that don't have a human behind them currently. If they didn't have that to lash out at, it would make people more accepting of the "World is Full" message I think.

2. It is forcing people who otherwise would log out and go about their daily business to stay logged in, but not playing. Surely, this is adding more strain to the servers and there is no reason in this game to encourage that is there? Every Aetheryte camp has a bunch of people standing there staring at the crystal and not moving for hours. Is that really necessary to encourage?
