I win a comp match and I get 10RR but I lose a comp match and they take 26RR... WHY??? How does Riot calculate who loses how much RR?? It's almost like they punish you for losing more than they reward you for winning.

How do they know that the quality of this person's gameplay matches up with the quality of another's gameplay?? What is the criteria to meet for the matchmaking?? I'm too inconsistent to even be good enough to play against an all bronze team or a bronze/silver team or even a GOLD PLAYER (had more than one gold player occasionally). It feels likes they're punching down on me and it's very discouraging.
