It's frustrating to be placed in matches where the team you're assigned to is already on the brink of losing because several players have left. For example, being added to a game where your team is losing 0 to 90 feels unfair.
I find this system demotivating. It’s not fair to be penalized for a loss when I’ve barely had a chance to contribute. Since the matches are short, it would make more sense to either end the game as a surrender when players leave or let bots fill in and finish the game.
