Change Alpha strike
Yi can use Alpha strike during the initial hit of heroic charge. I'm quite sick of being unable to do anything against master yi even with a heavy cc team. Yes, he can be cc'd by 5 people, if he's extremely bad. Master yi is unable to be light cc'd and can also dodge any other form of cc that isn't instant. Why give him such an overloaded kit? Give him one of the other. Don't give give fizz cc immunity, why should yi? Both are melee burst assassins with similar skills. Making your game more frustrating is only hurting the game.
