Ranked System

Is it just me or does riot have a fucked up ranked system? I win 10 in a row, and then I lose 15 in a row, this is not just a coincidence because it happens every single time. It is often said that you should a take a break after a couple losses, but it seems as though everything I do is useless. The ten games that I win are extremely easy, my team and I always dominate the enemy team, but the games where I lose feels as though the players got 20x better. Most people say its psychological and playing with an angry mindset will often result in a loss, although this is true this is not the case here. During my streak of losses I often encounter multiple trolls, afkers, and people who pick the strangest champions for their roles. ie. soraka top, etc etc. There was this one occurrence where I had to dodge 3 games in a row because of these mishaps, and when I finally got into a game it resulted in a loss. When I eventually win a game, breaking this losing streak, I end up in a even more annoying pattern of wins and losses. I win one, I lose one, I win one, and it follows this exact pattern for about 20 games and the cycle starts over again. I'm not saying riot is targeting me because they're obviously not, but does the league ranking system automatically make you lose games after a streak of wins? Or am I just going crazy? Because of this I believe that going on tilt only relates to people in very high rankings like challenger and diamond where each player is basically at the same skill level.
