I'm sick of this pathetic game

So i left the game since a while ago and came back, i made a new account couple of days ago and started playing league all over again, but so far my experience has been extremely bad.

My problem is not with the game itself as it might seem from the title, it's the community of the game. So toxic, tilting, annoying, childish, entitled and pathetic.

For example the last 2 games made me seriously reconsider the possibility of leaving league forever because of how toxic the players.

In the first game of the two, our ADC decided to pick Ahri, i offered him an advice and told him that Ahri is not a very good pick for an ADC, you know what he responded with ? "It's not ur bussiness" in a really blunt manner. I told myself maybe he's right and he's entitled to play with whatever champion he wants and just went to the mid to do my job in the lane, but did he leave me alone ? Hell no. He started calling me useless trash and started making fun of me and saying that i don't want to give him kills because i'm jealous and kept talking about how wrong my runes are even though they weren't wrong and i can't even have custom runes because i'm still low level and he kept bragging about how he's gold 3 with 700K on Ahri and that i must be a loser bronze 5 and he simply never shut up the whole game and tried his hardest to tilt me in the most passive aggressive way possible (also taking my farm and trolling my lane). I kept a cool head and we won the game and i responded to him that he's a sad frustrated person and " :))) " to piss him even more and then muted him.

The second game was even more tilting and toxic. I picked the mid lane and then i found that Wukong with the name "main midlane" instalocked and went to the mid even though i said mid before the game started and he said nothing. He told me that the mid is "his lane" because his name is "main midlane", which was both hilarious and pathetic. The whole team started flaming him, but we had 1 top against a duo and 2 bot and we were 2 mid, i decided to bite the bullet and swallow my pride and go help the top because the team is more important blah blah blah. As soon as i took one minion from the top whose name is "Hi im a lady" (he isn't not a lady by any means, he's just a horny 14 years old at best), you know what he did ? He fed the top, mid, bot and trolled the whole game, for just one minion. After the top was fed i lost against a fed Master Yi and Taric, which is expected and you know what my lovely team told the enemy team ? They told them to report me for being a "noob feeder", like WHAT THE ACTUAL %%%% ? And they kept flaming each others non-stop and i kept getting more and more tilted and at that point i lost it and called them all worthless and then we lost the game.

Those are not the only toxic, tilting games i encounter, nearly everyday i must play few of those games until i get frustrated and close the game. Will Riot ever do anything about this shit ? I'm afraid if this continues, not only me will leave the game, but a handful of other summoners as well.
