It doesn't stomp randoms though. On every team there will always be a great player, a bad player, and a few in the middle. It will be reflective of the community. Bad players always playing only bad players is dumb. Good players always only playing good players is dumb. Good player should get to stomp bad ones. Bad ones should get to be stopped. You talk about improvement. How does someone awful improve if they only ever play awful players? Most people learn by facing a challenge.
