I think the window to amplify changes when it hits as a KB for whatever reason. When you get the KB , amp after the punch. With regular counter amplify when JC is about to throw them.Somebody please explain to me how to amplify the mime counter. Sometimes it works for me, but most of the time it doesn't. I've been landing the crushing blow a lot recently, but I can never get the most out of it. It's like the weirdest fucking move to amplify in the game.
