OK LEAGUE OF LEGENDS

Hello all, so I found a new very good champion, Trundle, and i went on some win streak to get to Plat 1. So what does League of Legends do after that? They match me with incompetents and favor the enemy team, so I believe. I find no other reasons why I should ever lose to stupid champions top such as Fizz, Renekton, or Singed. So I've come to the conclusion that Riot fixes games to the point where they put players on a losing streak purposely by secretly giving champions buffs through the loading screen. There is no other reason I should lose. So after I do lose, I go on massive tilt and lose. This might not make sense but there has to be someone out there that feels the same way! I don't know if anyone cares but I thought I'd share this. RIOT MUST BE STOPPED, I WOULD LIKE TO GET TO DIAMOND!
