Yi/Taric Boosting strategy in Plat elo.

Im just so sick of this. I literally met Yi/Taric boosting duo like 10 times already in this elo. And literally, nobody knows how to counter because we are in plat elo. Mid lane doesn't push the wave, Jg just rage quit/give up every single game. It's not my teammate's fault though. Because they are Plat, I can't flame them. The problem is these Yi/Taric boosters. As you can see in the link, His flash placement CHANGED as he started duo boosting with that strategy. There is so many accounts like this in Plat. I literally lose every single time when i meet those players, and just don't want to play this game anymore. It's not competitive at all. It is so obvious that THESE ACCOUNTS ARE BEING SHARED BY MULTIPLE PEOPLE. Flash placement changes, wr change, etc... I don't even expect riot to remove all the boosters. Because it is impossible. I just want them to balance this YI/Taric, Lulu/ Twitch strategy. Please riot. I beg you. I literally just want to quit this game whenever i meet that strategy. I'm sorry if this sounded offensive/rude. I just want a better league community where players can enjoy their game and play competitively.
