Ranked system suggestion

Greetings, Climbing the ranked ladder is not only frustrating but can be even worse when you lose because of something that isn't really your fault. For example, you do well and win your lane, but your other laners feed and it ends up costing you the game. I doubt this will even get looked at by anyone or seriously considered, but I'll try anyway. Ranked games should dish out or take away LP based on how well / poorly you did in a game. If you carry your team, you should get more LP for that rather than the bot lane you carried getting equal LP for doing close to nothing. It's tiring to lose LP based on your teammates' bad decisions that ended up costing you the game. Thanks
