BAD pairing and classification system

After they match people with a bad reputation, they also leave your team and the games count, they lower you of rank and everything, ah but when they leave the enemy team and you win they do not raise anything, Lag that favors the one who has it, bullets that don’t count, bullets that disappear, campers even in the soup, what’s next? steal cars? swim with homeless people? Fix your mistakes instead of entering more modes.
In the case of the campers do something because they are not normal for the whole game, put a time limit to be in one damn place.
