I don't have a lot of friends in IRL who play league and my wife doesn't really get it. I need someone to see this game. 2 trolls playing Hunger Games Jhin on my team. 1 troll on the other team playing Fast and Furious Snowball game. It was one of the funniest silver shitfests I've ever seen.
I think is the best way to handle trolls. Laugh along, remember it's just a game. Do your best to win regardless, and report as necessary.
