So I just played with a Rioter...
I just finished a Ranked game with Riot Asyrite, and a few weeks ago played a normal with Riot KateyKhaos, and you know what? They were the most chill, laid back, fun games I've had in quite awhile. Nobody raged, nobody trash talked, and nobody was toxic. The one person who did start in on the enemy team when I was playing with Katey got real quiet when they realized. The fear of retribution is real.
It just sucks that people have to be watched over constantly to not be jerks. My game tonight with Asyrite, who absolutely crushed it from the jungle, was the least toxic game in Plat I've had in weeks. People should really go into each game as though somebody from Riot is watching what they say. League would be such a better environment to play in.
