This applies mostly to FFA and 2v2 but it would be nice if lobby instance weren’t forced to close if even a single player opts out of a rematch or leaves during character select. For FFA and 2v2, it would allow players who want to keep playing with each other to do so and the matchmaking could grab somebody queuing up to fill the vacancy. For 1v1s it isn’t necessary but would be a nice quality of life fix to be able to stay in your own lobby instance and wait for matchmaking to bring people to you instead of having to return to the main menu to queue up again.
