I can't stand the ignorant people in here advocating for people to be able to stay in the game 24/7 afk. Seriously? If you aren't playing then you should be kicked out of the server. If you are going to just stand there all day, you aren't doing anything but wasting server resources and making everybody's game slower. Not to mention you are taking up a slot that someone who want's to actually play can't use.

Quit being stupid. If you aren't going to actually play then you have no reason to be in the game.

15 minutes is more than enough time for an AFK kick timer. If you get kicked and still want to play then you can log back in. In the meantime it will fix the congestion issues and allow everybody to actually play the game.
