Firstly, why did the game even start before finding us a 4th? Then secondly our teammate leaves immediately only for us to play 2v4 the entire game and lose by 2 points. what a shambles of a ranked experience. Sort this out. Ranked is supposed to be competitive. I am now 1 loss on my placements due to nothing less than an awful matchmaking system and a game that promotes people leaving.
Same thing happened to me, the game started with our team with 3 players, then once the second player left I just quit to, no point to playing.
