LP system.

Really wish riot would change this broken system. Just played a game I go 10/4 top lane my lane opponent goes 3/7. My teammates scores are 2/7 3/7 2/8 1/5 sure its a team game but when I do so well and win lane and everyone else feeds and then my lane opponent gets a boost in lp and I lose for going 10/4 and not being able to carry that awful team. I mean If i could carry them that would mean I would be good enough to be a division or two higher. How does this really judge a players skill? I understand its a team game, but if every other lane loses its nearly impossible to carry that, it is "SOLO que" so why are we all judged as a team when I que up solo and riot picks awful teammates for me. I really am not sure I have a solution that would work but I know something needs to be done.
