The last few games made me really really sad

I have never played with such toxic people.

Enemy threatened to report me because I beat him in lane. Our Adc and Jungle are cussing each other while our mid is 0-11. The enemy team was also constantly harassing us through chat and everything else was just one horrible roller coaster ride. We surrendered at 20:00 not because we were so far behind, but because of the amount of toxicity.

And what's worse is that the previous 4 games I played had similarly toxic players.

Riot, PLEASE DO SOMETHING. Like maybe reward positive players? It would encourage people to be less nasty, Jesus...
