Should Riot Games Fix The Ranking System and How?

I honestly feel that the ranking system in league right now is preventing players in low elo (primarily bronze and silver) to be able to climb, espescially the good ones. I don't feel that it is fair for players that do good get punished for their teammate's failures. I understand that League of Legends is a team game, but isn't ranked solo/duo que testing the players individual skill in a game? I feel that players who do really well in ranked games and lose shouldnt lose like 16-18 lp and lose around 4-6 lp. If a player that does really good should also earn 24-28 lp instead getting the same amount as those who got carried. Riot please take this into consideration thank you.
