Re-work Master yi

most people would disagree, i know that but yi as a champ and the way he can can be played bugs me somehow and i get a little frustrated. For me i think yi is isnt a champ that can be the game changer when you are losing the game. It's like a game of rock paper scissors, he could win 1/3 chances, and he can loss 2/3 chances. Some people say nerf because he does to much damage, im just saying to re-work him some how
