Death Sworn Katarina - Sound Effects
I have checked it sometimes thinking that it was just me but then (after testing it a few times) I noticed the Live version has "smoother" sound effects than the PBE version (after the release and even now).
I know her ultimate was really loud but "dramatically" decreasing the sound effects of other abilities in a way that you have to increase the volume of your computer to 80-100% (and even then ...) doesn't seem necessary. Personally, the PROJECT version seems to be perfect in terms of intensity of sound effects and I think this skin should take the same approach. I would say that her Q, her passive and her E are almost inaudible.
