Ranked Point system

Hello. As I play ranked game this season, I am very doubtful that the rank reflects the individual's skill level. Last season, when I played solo queue, I would have over 80% win rate when I win during laning phase and do well rest of the game. However, this season I believe I don't even have 30% win rate under same conditions as last season. The problem is that because of low win rate, I only receive about 17 points when I win, and lose 20 points when I lose regardless of my performance in the game.

There are a lot of friends around me complaining about the dynamic queue, scripters, and the ranked system which are leading them to quit playing league. As a 5v5 team game, I know that you can't always win a game even if you do well. However, I believe that individual's rank must reflect his/her skill level. I think by setting the amount of points players gain/lose depending on their performances in the game would reduce complains from player. I understand that you are very busy making new skins and champions, but I believe that player satisfaction must be the priority over anything as a game maker. Please consider my suggestion.
