Individual Ranking Avaluation

So as a king of bronze i get a lot of trolls... not talking about those who simply does not know how to play good yet but those who simply do not want to play or intentionally feeds the other team and keeps the entire game flaming or cursing the team.

So,

i was thinking that Rank games should have an individual rating

Ex1: Lets say that "playerX" ends an 30m game with 3 towers destroyed, 1 inihib, 15-0-6, manages to do (or assist) the drake and baron but still looses the game while "playerZ" flamed the entire game did 0 objectives got a score of 0-12-2.

For me that playerX should be rewarded for his performance individually. Yes the team lost but he as a player did well and therefore shouldn't looses the same lp as the playerZ that's just unfair and frustrating

so instead of loosing 16LP the playerX should loose lets say 5LP and meanwhile the playerZ should loose 20LP

In this way players who want to play rank competitively would have a way to minimize damage done by those who only concern is to be annoying .

Ex2: This time "playerX" didn't do so good and ended up with an 2-8-0 score, no drake or baron involvement and only 1 tower destroyed and somehow he managed to win this game because of his teammates who carried him.

In this example "playerX" should also won less LP than his teammates meanwhile the best player of the team should win more LP

So basically i wanted an rating which rewards the best players of each team and punish the worse players. In this way everytime you ended up with a troll or a feeder you still know that nothing is lost and you can still minimize the damage or even rise above all others

its my first post here and im not english native... sorry if its too confusing and please discuss this

Thank you for your time
