What Riot Should Do To Ranked

So I love league. It's my passion and it's the only thing that even makes me happy now. However I become frustrated and annoyed with the rank system. I frequently do exceptionally well in most games, I rarely feed and I am supportive and non toxic towards other players. However I repeatedly lose these games due to a 0 group push effort made by my team, yes i am low in the ranks but i cannot get higher if i have players like this over and over and over and over and over and over and over and over and over and over and over. Now if i do bad i accept the loss, but if i did well i become upset that I loss because i'm always giving it my all and this is why i think they should introduce a new LP/rank system.

So for team 5v5 i understand giving the LP or taking away LP based on the word victory or lose. However for solo q or maybe duo i think lp should be given out on whether or not you did well opposed to win or lose. This way people dedicated and giving it their all in every game can progress to a point where this is not needed as much and they can actually begin to work with players that feel the same and communicate well and play well. I'm not saying complete remove the current system of win or lose. i think win or lose should still affect the LP for a base and then depending on how you did it adds some on to reward you for doing better.
