The Ranked Ladder system needs a rework.

Now, I'm all for the bronze-silver-gold, etc. but i'm getting sick of doing well in a game, losing because of one or two other players, and losing LP or even a division when it's not my fault. All i'm saying is, put something in place where we earn LP based on our personal behavior in a game so we don't get screwed by the top laner who went 2/11/0 against a Riven who then carried the game. As a support main, I feel as if I help my team accomplish goals that are more important than kills but in the end it just results in a loss because some new level 30 decided to play ranked and queued up onto my team, I'm not saying it needs to be perfect, just that it could use a few adjustments to compensate for potentially horrid teammates.
