Whenever I get a Yasuo on my team...

I am not even trying to be mean when I say this: Do not pick a champion into a match up, that you do not know how to play. It just isn't a good idea. No matter how much you see people calling a champion broken, do not pick them for an easy win. You never know who how skilled the person who your opponent is. It is incredibly frustrating and just ruins the ranked experience for everyone.
