I think everybody can agree that you misunderstood my post I was talking specifically about HOSTS quitting mid-game, because it would instantly kill the game for everyone else. At the time host migration was broken so if a host quit, the round would end with no rewards for all the clients who connected. And it would take a good couple minutes to get back to the lobby because it would try and fail to migrate to a new host.
THAT is what I wanted to penalize. I had zero problems with clients leaving the game on a whim, same as now.
