Crystal ranked players past a certain point threshold should no longer get Diamond players in their matches.

Sure crystal players can be good enough to carry lower ranked teammates, but it is neither fun or rewarding. Instead of matches of even teams where a loss feels "close", you get teams of people trying to win paired with teammates who haven't even read a rulebook and are stuck at Diamond 5. These losses no longer feel close but "unfair" and more like a cointoss.

This is neither fun or rewarding. It is just frustrating, and it only breeds animosity among players that do not perform.
