When a team creates a 2vs2 league game, they have the possebility to cancel a game without loosing points, if they get from the system a player out of the random league 2vs2 - instead of another team.
In this case, with one opponent, the beginning team can choose if they want to play that game or not. When the third player (so the second player from beginning team) dont move or hit the “give up” button, the game is finidhed without any impact. Because the 4th player slot “waiting for more” only search for the right player for this game, when the third player made his move.
It can not be, that you can choose in a league game against whom you want to play or against whom you dont want to play.
In my opinion that is against outwitters spirit. If you want to be good, you have to survive bad and good situations.
