Well in retrospect, since people think modern mmos do not have a logout timers here is a list of some that do, in no particular order:

WoW
SWTOR
Star Trek Online
LOTRO
Rift
GW2
Neverwinter Online
Aion

And that's just to name some current and popular MMOs. (lol @ maple story and vinductus). It's industry standard and common practice to reduce server load, even when servers are not maxed. It makes smoother play for people who are actually playing, regardless of it not being capped at the moment. There is NO valid argument against an AFK timer as it takes 5 seconds to log back in, and people who do other stuff while in Q can tab back in every 25 mins to press A button. Not the end of world. You can QQ all you want, this wont go away.
