this is something that typically happens when you run cleanse in higher elos , it turns into a stun deterrent. its just like building a QSS vs a mord and then he never presses R on you and you never need to use the QSS. or he hits R once to find out you have built QSS and never dose again.
Ya he is awesome, really makes the moments hype. I wonder how he does it. I'm sure some sort of voice changer program/voice modulator like a Roland and probably has soundboard presets with the crowd sounds. But I'd really like to know for sure what he uses. It's PREFECT!
