In-game: 2 or 3 minutes.
Game room: 5 Minutes, maybe it can be reduced to 3-4 minutes.
There's no reason to make it any longer for AFKers, they can afk on lobby.
I guess we could try 3 minutes in-game and 5 minutes in stage. Plus perhaps kick you from in-game straight to lobby, instead of to stage (since you're AFK anyway).
