How To Balance Pyke's Heal/safety

This is what i think , right now the way pyke works is u dish out all the damage u have , cc him as much as u can and pray he dies during that or he just e/w's out and is back to almost full hp. What i think pyke's grey health should work like is if he is in w and he gets cc'ed not damaged but cc'ed (hard cc) his w should end or atleast reveal him for the rest of the duration. Its so unfun to play against a pyke , u deal ur entire combo on pyke he goes invisble and comes back , u do the combo again and he does the same thing 7 seconds later
