Riot when creating matchmaking
This is the transcript from riots actual design team when they created matchmaking
Paul: Alright guys we need to change our matchmaking to better suit our totally unique game.
Jim: We thought it was okay, what did you want to change?
Paul: Well instead of matching players of their rank against other players of their rank, what if we matched them. Off of their skill?
Sally: Wait I'm not following.
Paul: Bear with me, what if instead of matching golds against golds, we dropped some diamonds in their game, you know. Show them the hard side of casual gaming!
Jim: That sounds terrible
Sally: Yeah that is absolutely fucking retarded.
Paul: What do you mean? I'm talking, what if some gold player who won a few games thinking fighting other gold players is easy. And BOOM we drop 3 diamonds in his match.
Jim: THREE?!
Paul: Well it'll be okay because they'll be qued with a silver.
Sally: Well what is the gold qued with?
Paul: also silvers. Like I said, this is one tough cookie he won 3 games IN A ROW! Gotta try him to LCS amirite?
Jim: That's terrible idea..
Sally: Absolutely awful
Paul: Well I already did it. So get the fuck out of my bathroom.
Jim: This is a conference room..
Paul: Then why do I shit here.
That's about how it works. Playing normals or ranked and you fight diamonds EVERY FUCKING GAME! Along with 5 man premades and they wonder why you do cocaine.
