To keep things simple....
-i think we should remove the logging off due to idleness thing. (it gets really annoying when you solo a run and something comes up and you have to afk)
-replace it with an AFK button. (If used during mid-game other players may continue without you (or choose to kick you)) also you become invisible to enemies (esp useful when soloing) however you shouldnt be able to spam this because it should not allow you to move and you should still be able to take damage (so it cant be spammed just before an enemy attacks)
