The matchmaking is so bad that in almost every game after ~3 min one team gives up and goes afk, so why not just let us save time and end faster?
Just like gw1 had the /resign we also need it, so that when the matchmaking puts you in a game that will end up 500-100 (aka 4 out of 5 games) you and your team can go through the motions faster and move on to the next blow out game.
see no evil ,until i stab you
