Because Jhin.
Seriously, though, I love the game. The art, the lore, just the style and feel of it. I just despise the vast majority of the community, and that's what keeps me from playing most of the time.
I can mute toxic chat and pings, but I can't do anything about my autofilled support picking Draven, calling me an animal, and demanding that I support them.
I can't do anything about my Nautilus abandoning bot lane after I miss a single skill shot and AFK farming jungle for the rest of the game while arguing with the Xerath, who is also AFK farming the jungle.
I can't do anything about the Poppy and Fizz duo that used their abilities to get past the turrets and suicide into the enemy fountain.
I can't do anything about the Jax that called me useless and AFK farmed the jungle/inted, even after I made a comeback and gave the team a lead.
I can't do anything about the Rakan who afked after he died and then proceeded to leave base, walk past his teammates who needed his help, hit some jungle camps, recall, and afk again, saying "get fucked, idiots" post game.
This community just makes playing this game a damn chore no matter what gamemode you're playing. If its not flaming, its inting, trolling, or just... Something, anything to ruin the game and make it as unfun as possible.
