The toxic world of league, and i'm not talking about twitch

I stopped playing ranked games for a good three or four months as I decided that I wanted to wait until I was better so that I might go into ranked with a better idea of what I was doing and it might make situations in ranked a happier time. I queued up for two matches this morning. Both had multiple people who argued about nothing and used offensive language and both also had multiple people who fed because they wanted to make another angry. How does this toxicity exist and how come after the tribunal being fixed up for so long is there no improvement whatsoever with Riot's report system. The system still allows for random people to get banned because three or four toxic people ganged up on them and it still allows for all sorts of hard R's and insults to be thrown out to whomever one wants. There are multiple easy fixes you could use to correct chat problems and there are a lot of ways to fix issues with feeding so why have we players in the community who just want to play seen no improvements? Ranked should be a great time and normal's should be a good place to practice and play at your leisure but why are awards being handed out to gold players at the end of season ( as toxicity exists outside of lower tiers) while there are people playing really well in lower who keep getting matched up with feeders and griefers? There is so much room for improvement on league and for a player who has so much love for the game and it's community I really hope that Riot cleans up their act and does something to show players that you can have fun and tease with your friends but anonymity does not mean freedom to be a horrible person and use language that if used in public would get you in some serious trouble. Sincerely, A player who is having a really terrible time.
