Match Makin

I have been stuck in bronze for going on three years. I am very frustrated with your ridiculous match making program. If I get on a winning streak you team me up with worse and worse people until I am on a losing streak, then you team me up with better and better people until I am on a winning streak repeat. My point is LOL is a team game and although I feel I am much better then most of the players I have been playing with for the last 4 years I am not good enough to single handedly win a 10 player game or defeat the inevitable team of people who are better then me while playing with trolls, inexperienced, or apathetic players you eventually pare me with if I get on a winning streak. My point is I don't want to win exactly 50% of my games, in fact don't really care about winning or losing at all, what I care about is playing, and I do not get to do that if you team me with trolls and the like or against them. Why do you not just randomize so everyone available to play with in my division plus or minus 1 or 2 or what ever deviation you see fitting so if I am better then the average bronze I can climb until I find the right spot for my ability level? I don't want to play with people who are way better then me or way worse so you all can make sure every one gets to win 50% of there games. Let my ability sort out when I am at a level where I can be around 50%. I love your game it is something I play with friends and families, I have spent hundreds of dollars on skins and the like. I am willing to invest and I bring people to your product, but after 4 years of you making sure I cant win much more then 50% of my games I am close to having enough. Obviously if you cant single handedly win a ten player game unless your Faker then you give me worse and worse team mates while giving me better and better completion to ensure I cant climb. 50% does not climb, just randomize it and skill and the ability to work with other players will sport it out. But you have made this giant complicated system to ensure I can not climb? WTF? I want to play like I said don't care if I win or lose I want to play, I value my time. SO please for the love of god let my ability decide my win ratio not sabotage me or even stack the deck in my favor to make sure every one is at 50%. Don't you see how frustrating this is?
