I propose an addition to the game, the option of a rematch.
When a match is completed the host may press rematch (located above or below leave game) when the host does this each player in the match receives an invite popup. If they click accept they automatically join the rematch. The rematch would be the same setup as the first match. The rematch would be a locked match which means only players from the previous match could play.if a player denies the rematch or leaves the game too early to even get the rematch popup then the invitation is given randomly to a spectator. In the case that no one joins the rematch the host may untoggle the lock and then the game is unlocked and continues as normal.
