Ranked System

Many people is complaining about their rank and teammates. They are angry when they lost even if they had great score and farm. I was thinking how about at the end of the match, even if you lose or win you get LP, game will look at your score etc. Supp Leona had 2/4/20 and he lost the match. He will get 5(plus or minus) if they were good like this or 5 minus if they had low vision score as supp or negative score. This would improve LoL ranked system and for many players LoL will be fun to play again.
