A friendly reminder to everyone in low ELO:
Stop playing Yasuo. No seriously, he's a high-skill champ. And if you HAD that high skill, you would definetly be not sitting at the ELO we are currently playing at. (low gold in my case).
I have seen this only with Yasuo, with not a single other champ. mostly the end stats are something like 1/7/2 or something, or maybe 2/8/2, doesn't matter, you made your team lose the moment you picked a champion way above your level. You want to win games and climb in ranks? Then play champs you can actually play. When you made it to plat you can try picking him up again but until then it's a bad idea.
Thank you for your attention.
