thats why eventually they give you a good game with carry players, and the other team is on the receiving end of the hidden mmr system. its a never ending cycle.
Keep switching sensitivity until that starts happening less. Everytime I switch to high sens I match MVP like 3 games a row but that's honeymoon phase. Then I MVP and go 0-16 like you said and have to go back to lower sens to perform more consistenly.
