Just had the hardest game of my life...

Played vayne top, vsing a hec, got camped a bit at the start, morgana mid was roaming bot, our cait tilted, yi tilted and yelled at everyone. We were on the verge of losing, i triple them down. From there I lead the team, told everyone to stop arguing, but our yi continued to flame everyone. It was a struggle, but eventually after I got big everyone realized we could win, everyone but yi focused. After that we just won. My god the things I have to do to win a promo haha. Atleast I'm plat2 now. I felt like I was babysitting kindergartners in a game. What was a struggle you've had?
