Isn't this a little suspicious?
So in my ranked game, being silver 3 trash, I got 2 people on the other team, both silver but one plat last year and the other diamond that I was facing against mid lane. We lost the game but mid lane certainty wasn't playing like a diamond or I would of gotten obliterated. I called them out on it and one said "I'm boosted". I don't know if that was sarcasm or not. I didn't bother reporting them mostly since I forgot I was arguing with someone on my team....
