Intentionally Losing to Gain LP?

TLDR; IF i win 15, I'll lose 15 in a row, because Matchmaking seems skewed to hurt you for losses and praise you for wins. Win 2, intentionally lose 1 and you'll end up climbing more consistently (theory).

I've had many experiences of this; I'll win 15 games, lose 8 in a row. I don't believe tilt exists, I believe that matchmaking is so broken that it skews results based on very minute details of the games I play. When I win a couple, it automatically puts me with higher skilled players. But when I win too many, all of a sudden I play with 8 teams where every lane loses and I'm lost wondering what happened at 20 minutes when we have 45 deaths.

So my theory? I win 2, intentionally lose 1. That way I constantly climb, and don't have to deal with the last 8 games where 2 lanes lose by humongous margins because "I don't play ziggs" "you're duo with the jgler aren't you" and the best of 'em "Why didn't you come before I died 9 times to fizz?"

Am I wrong? Do I have to intentionally lose games while maintaining my stats just to win? Because apparently Try-harding only gets me on massive win streaks and lose streaks, and when I lose I continue to lose because I believe matchmaking keeps lowering my mmr on the basis of my deaths. I refuse to accept that "Tilt, it happens to everyone" is an excuse for a matchmaking system that punishes those who endeavour to win.
