League's biggest problem

The biggest problem with League of Legends is the assumption that everyone WANTS to win and/or be the best they can be at this game. People make many suggestions every year to try to improve toxicity and trolling and the response is always "that can be abused". Over the long haul, I THINK (this part is my opinion) that this has caused a large number of low to mid tier players that DO care about their rank or having good games to leave due to the sheer frustration of continuously playing with and against: trolls, smurfs and afks, NONE of whom care about those things.

I had a game a few days ago where mid picked Nasus. When everyone on the team wondered why he flat out said ranked doesn't matter and he didn't give a shit. And that's one of the few that actually explicitly ADMITS such things outright as opposed to the tone of people who don't, they just ruin the game "silently". Are we really worried about the miniscule portion of players that will abuse an idea to rank up that DON'T bother availing themselves of one of the easily found boosting services? Are our challenger/high-elo overlords really THAT worried about a couple of hot-shots that stay held down by endless trolls? How high do we really think someone can get simply because they "cheat" the system to avoid obvious shit games?

And I don't want to hear the BS about how players will "bully" someone into helping them out. You're hiding behind a computer screen, keyboard warriors already try to "force" people to forfeit at 15 all the time and other players mute them or intentionally vote no JUST TO PISS THEM OFF. Who are the fragile dolls that still somehow miraculously play this game that would let themselves be bullied into helping assholes?
