I've saved a few games cuz of two persons trashtalking to eachother, like this one:

Actually, I've never seen two salty players fighting eachother.
Real talk: I was fed, but I principally told them that it's the best way to throw the game, and that if they don't stop, I'll simply report them.
Well. I told them I'd report them if they don't stop cuz I was fed, and they couldn't say anything since that I was fed. If I wasn't fed, they'd just say how trash I was, and stuff.
Bronze and silver are just full of toxicity tho. It's another world. For now, I didn't saw a lot of people being salty, and I'm glad, but I know it'll happens no matter what.
EDIT: Before people tell me to not care about, I do care about. I don't want to sit there, watching people talking shit to eachother just because they fed a little bit or something.
I played as well, I just told that in chat when I was back in base/out of a fight/dead.
