See I agree with the OP, when I am not running with the FC and pug something with the DF I queue up and then go do work on my other computer waiting for the DF pop chime, and now if this takes more than 30min and I have not pressed a button not only do I lose my spot i get disconnected even though I am feet away from my game. Yes I can just hit a button every 5min, but if i'm busy working its not something I am going to be thinking about.

Suggested change is if in Queue and are AFK it stays logged in, but if it has been greater than 30min and you fail to accept the DF pop you are then logged out.
