Ranking System Idea

I don't know the system fully yet, as I am very new to Ranked still. But I have noticed that good players are punished by the entire teams failings.For example, you could get an S+ and still lose the match and go down in LP. Making harder for the better players to go up as the worse players go up on the wings of the good teams. Pure luck. No skill or not really enough to advance and they still go up because of the team. I've been on teams where I am the worst of both teams and still get a B+, and it seemed I got carried. More than likely that's true. But, there are also games where I Carry my team hard and we still lose and I pay for it. Even with a high rating. Can we base our going up in LP and down in LP based on your rating as well as the win/loss ratio? Like lower LP if you lose, but You still did good. And vice versa if you are bad. Is this achievable? The games that you lose would suck a lot less..
