Certain abilities get canceled when you Decoy and it makes it very obvious that you've decoyed.
For example, GP's Parlay. When you see a red highlighted GP running at you and you Decoy, GP stops running at you.
It makes it very obvious to other champs when you've used Decoy and when you're pressing S.
Even if you hear him load up his parlay with that click of him pulling back the hammer, and you press Decoy, GP's Parlay gets canceled.
