Tired of this matchmaking. Silver player all the time with Diamonds...

This is my second post about this same topic in same day. And there is reasons for that. The thing is that matchmaking is broken when you are under lvl 30. I'm currently lvl 27 playing only Rammus, my skills are something like high silver - low gold but I'm against games with full diamond/plat teams. I'm not against playing against much better player because ofc I can learn from them, but there is dark side of it. THEY ARE GOD DAMN TOXIC. I'm getting flamed in every single of those games, i'm getting death threats for being so bad at this game, they says like "Go kill yourself" when I'm talking them politely about my bad position in this matchmaking. You really get tired for that when you get "kys" in every single game, and when teammates just ff's because they don't want to play with "noob". There is nothing I can do, I'm just tying to learn from them but all what I learned so far that don't use chat or you will get insulted for rest of the game.

And is reporting only way to show to the Riot those toxic players. I think I don't deserve death threats for being just simple bad at the game.
