Great to hear (pun half intended).
Judging from the Skin Spothlight video, the mini Gnar Q On Hit is also quite loudish. I see you have done an analysis of the sfx's volume, so I trust you deemed it not out of line. Maybe the linked video exaggerates the effect. It may also be the case that the sound is more harsh than the kinda mellow base sound and for this reason I perceive it differently.
Yup! Q hit is also loud + a bit more harsh, it should sound a lot more soother to listen to now.
