Playing this game makes me want to hurt myself but I can't stop.

I've been playing League since season 3. I don't know if it's just nostalgia, but to me it really seems like it was a different game back then. Of course, people still trolled/raged/flamed, but it seemed like you could still find tons of friendly players. Nowadays, I have at least one player in every game telling me that I'm trash, I should uninstall, I should kill myself, etc. This normally isn't an issue, as I could just type something back and mute them. Unfortunately, I can't type anything now as I risk getting banned, and muting is the single easiest way to kill all fun in the game imo. This leaves me with playing through a 40 minute shitstorm of a game (because no one ever, ever, ever fucking surrenders, but that's a different topic) with 1-3 players constantly flaming me for every little mistake I make. I report them all, but I'm 99% sure my reports are next to worthless since my account has been punished before. I just want to have fun playing the game again. Aside from playing normals (biggest waste of time imo) and playing with friends (none of my friends play this game anymore), is there any way I can get even a tenth of the enjoyment I used to get from this game?
