the toxicity and afking is really ruining this game for me

I spent all last season climbing to silver. well like a lot of people, I went 8-2 in promos and despite that good record, got placed bronze 3. and now for the past 4 months I have been jumping between b2 and b4, and it usually goes something like this. Wins 15 games in a row, gets super confident, then I lose 15 games in a row, and its mostly due to afk's and trolls. My last game someone decided to go singed mid against a morgana. he spent the entire first 10 minutes diving morgana and fed her (mostly due to tower deaths) 5 times. I kindly asked him to stop diving her, and to play back. He decides to rage at me, and sits in the base the rest of the game calling me a faggot. (I am gay by the way, so yeah I was not happy about that). half the games I play have an afk these days (on one side or the other), and the majority of games are one sided because teams don't get it. Don't give me that BS old saying that if you deserved to be silver you would be, because I was silver last season. At least in silver the number of games with trolls went down dramatically...
