Kennen SFX Update feels like a downgrade

Kennen is my favorite top laner and had some of my favorite SFX in the game. In particular, I loved the loud, snappy pshhhhhhh of his W and the loud sound his stun made.

Since the update, I don't enjoy his sound effects as much. I did a comparison on the PBE before it hit live and it's hard to describe, but his W doesn't really sound "snappy" anymore. Furthermore, when I cast E, the previous sound made me feel really fast and excited. In comparison, updated Kennen's Lighting Rush sounds like a quiet fizzle instead of ball of pure lighting. I think the stun sound sounds less punchy too, which makes it harder to tell when you've actually pulled off a stun. My friend noticed this too.

His updated Q is okay, although I do prefer the older one. All this said, I think the auto attack sound is absolutely an improvement!

What was Riot targeting with these changes? Is there any chance for another iteration on this SFX update?
