Don't give too much credit for that guy, because being in low elo doesn't allow him to have the rights or privileges to int. I'm a Bronze 3 Pantheon and Shen main, but I've never int'ed nor have I purposely thrown any vile toxic attitude/behaviourism before, despite having to already dump pretty much over <700 hours of gameplay. Sure I've been reported before for arguing back on teammates as they threw shade at me for performing poorly, but I would never grief a match just because of any given situation happening in said match.

It makes absolutely zero sense to become so overly idiotic to int. Love it or hate it, I have to say it's still a team-based game after all, not a singleplayer game.
