The fact is that you cannot determine how laggy the game will be from the lobby pings. Leading to games which last 2 minutes then everyone leaves. This is Massively Annoying and causes people to stop playing all together. Lobby Simulator is a HUGE problem
Possible solution: Have a lobby button which runs a sizeable multiway packet test between all players, and shows which players are behind, just like in game. IDK if this is even possible.
If it isnt possible keep working on game based lag, there was a nice improvement to this last patch. Keep it up
