Ranked gameplay

Okay so I feel like it is absolutely wrong that I can carry a match and get nearly S rank but when my team throws I lose rank and get demoted. I am a support main and as such it is really hard for me to carry but if I do well I don't feel like I should be penalized, I would love to see a rework of the rating win and loss such as if you score high you get more points towards your rank but if you do terrible you gain very few even if you win. On the flip side of that I would love to see next to no loss of points if you do well even if your whole team throws. The upsides to this would be that even if you're losing a match your team is almost guaranteed not to give up in hopes of not losing points and being demoted, I feel like it would lead to fewer AFK's, fewer surrenders and more competitive game play regardless of how your team is doing.
