Statistical LP

So I've been climbing a bit and I am a Gold ADC main. I've been wondering if anyone thinks that there should be certain factors that go into consideration when a players MMR rises. I feel like it's difficult to climb because certain players that aren't as good as others can get carried and boom what do yah know, they can be in the same MMR. I feel like when a player climbs, their KDA and their CS should also be a huge factor. Including damage dealt, or towers taken, how many objectives were taken throughout the game etc etc. It's been a real struggle and I feel like statistical LP is fair because it's hard to say it's not my team or don't blame my team when I'm doing well but yet everyone else's KD is in the negative and I'm stuck trying to pick up for 4 other lanes. Please share your thoughts as I think that this should become a good idea and discussion to speak on.
