Matchmaking is a Joke
No matter how well you play, know your role, communicate, offer advice, pick what is good in the meta, what items to build, and etc. There will always be one player that feeds VERY hard. There will always be that one player who flames you. Ther will always be that one player that refuses to buy a sighstone at 20 minutes and blame the JG for not ganking, when in reality if you just warded you could see the enemy jgler hiding in the bush waiting.
The ranking system for Bronze-Silver is VERY bad. I have never played with this much toxic players in a very long time. I climbed myself out of Silver and into Gold solo Q and refused to touch ranked. Well, stupid me, I decided to play Dyanmic Que and got placed in high Silver. I now I see all of the toxic little two year olds that are playing. It's even worse because you can have one player sit there and do bad but their premade will all report you for giving helpful advice.
It's toxic Riot. It really is. I got called a fa**ot by two premade players and I somehow get chat restricted for refusing to fight in unnecessary teamfights and telling our Support to buy a sight stone at 20 minutes into the game. The person playing the game and trying to farm up, gets called derogatory names and gets chat restricted. The matchmaking system is not matching adequately leveled players together and this has been a problem for years now. Even when I played Solo Q and tried to get out of Gold, I got three low Silver players that fed and we lost the game. I'm talking about the same types of players that are in Bronze that are toxic and in that division for a reason.
Fix the matchmaking system. Thank God I got Gold this year and I don't have to touch this garbage that you cannot be bothered to fine tune. Put toxic low elo Bronze premades against their own kind.
