Urgot R

Recently when I decided to go and do a troll match with friends I went to bust out my old urgot (Battle cast <3)

I noticed that when you use his R it no longer feels "Responsive"

Know how when you use abilities and you hear a distinct sound to know your ability worked right, this ability it lacking it and as someone who relies heavily on sound in games not having this clear indication can make for a clunky feel. Anyone mind looking into this?
