Ok why am i getting new players in my games?

I just had my worst experience in League ever and my worst game with Fiddle, Top lost 2 towers under 12 minutes... I'v never ever been in a game were a lane has lost 2 towers that fast ..... The support dies 3 times in a row. Why is this matchmaker is bad.... Its like when you go over 50% win rate it forces you to lose no matter how good you are at the game, if 4 players on your team are bad then its lost from the start, I'v tested this out myself and its true, When you go over 50 % win rate, You get weaker team mates and the other team get stronger team mates, Its been proven, Its on the boards somewere https://boards.na.leagueoflegends.com/en/c/gameplay-balance/Y3VGdqvV-a-statistical-analysis-of-how-matchmaking-is-unfair-should-the-team-elo-or-map-should-be-balanced
