How does the ranked matchmaking work?
I have a feeling it matches you with lower MMR players on your team when your MMR is higher than the division you're in. The reason I say this is because almost every game of ranked I play I lose, generally because my team/1 of my teammates is feeding. (I know, I have a couple bad games here and there, but generally I don't start to die a bit until after the enemy gets fed) I prefer to play tanky junglers, and most of my deaths tend to be for trades that are worth it/saves on my adc, so my scores don't look great. But when I lose 13 LP for a loss and gain 25+ for a win, i can honestly say I think my MMR is higher than G4. And before you say "it's always your fault you didn't carry", take note that I've seen a very alarming amount of 1/8 scores on my team at one point in the game or another.
TL;DR: Does higher MMR lead to lower MMR teammates?
