It would be nice if at the end of a game players could vote for a rematch.
Some lobbies are more interesting than others for many reasons, such as balanced teams and good comms. Also, a rematch can be appealing when the score is very close. Plus, when the game ends, you have to look for a new lobby again and probably wait another 10 - 20 minutes for a new game...
What if at the end of a good game most of the people would like to replay this match and continue playing with the same people? Say in highlander 16/18 players want a rematch, you find a quick sub for the one or two players leaving, and here you go, you wouldn't have to wait for another lobby to start, a lobby that is potentially less fun (teams unbalanced and bad comms).
You save time, you play more, and you get to know teammates a little bit better.
What do you guys think?
