Continuing the discussion from Bug or suggestion ? - Capture The Flag can lead to 2vs1:
It’s the “a player leaves the game as it starts” that bothers me. If there is enough players in other games, it will say “Game start in x seconds”, but if the amount of players get too low, this timer will stop. In Capture The Flag Duo, it’s not the case.
We just witnessed a situation where we entered a waiting room, “game starting in 20 seconds”, there were literally only us two 
Something should really be done to prevent not-2vs2 situations happening.
