Can we do something about this deranking system?

Like, im not even kidding anymore this is starting to get extremely fucking annoying. 3 games in a row, my score's positive, got the highest damage output in the entire game, and i lose all 3 of them cause my team is just garbage. I've played on EUNE, went with a Gragas toplane pick, went 9/3 with the highest damage dealt in the game while my entire team was 0/5 support, 2/3 mid, 1/7 jungle, 2/5 adc. I don't know about any of you but im not really liking the part where i get demoted because my team sucks, rather that i do. Can't we change something in the system so it can recognize good players from bad players and keep them safe on 0lp if they lose a match? This is getting absurd at this point.
