Something needs to be done about terrible players playing only Yi up to diamond.

There is definitely an issue with this champion when you see terrible players playing only Yi, and they win 75% of their games. Yes he can be countered with hard cc, but when he's picked 4th or 5th and your laners have absolute shit picks... it's pentas all day for Yi after 25 mins. Something needs to be changed. He needs to have the slightest bit of skill requirement other than (enemy team area CC) Q, auto auto auto Q, penta. Make spells cast while he goes in alpha actually hit him, make him have to throw a skillshot of his sword into the enemy for alpha to proc, nerf the length of his ult... something.
