Pyke's W isnt really Camo
Camouflage reveals the champ when they're near like standing close to Eve or Rengar when they have their camo up you can target and see them
Pyke you just get an indicator over your head to show that he's nearby but no indication of which direction and cannot actually hit him until the stealth breaks. IMO he needs to be revealed if he comes within a short range of your champ so you get some time to react or so he cant just screw up then W away when you stand right on top of him
