Master Yi rework please

I was just in a casual match because I'm not in my chemical resistant suit to play ranked, there I found some decent players. Then there was this Yi... Oh my. Riot really needs to get rid of cutting and pasting Yi from the game for 2 seconds and allowing him to deal damage while doing that. I understand that Yi mains are used to this, but this man has a heal, a speed ult, and a way to disappear from the game in an instant? Silence can stop him for a few seconds but without a Malzahar ult or some form of hard CC, I don't really see a way to kill a fed Yi that has GA. I'm just trying to say that I think it'd be nice if he wasn't untargettable, or at least reduce the scaling because this man hits like a truck and can lower the cooldown with autos, and with 2 or higher attack speed his cooldown is basically nonexistent. It's an easy way to win games without requiring the ability to aim skill shots.
