A human child is a smaller human.
An adult yordle is about the same size as a human child.
How big is an angel? The same size as a human, but with wings?
I realize it's a lot harder with Kayle because her wings are so big and her wings are iconic. They look great, they feel great, having huge wings is awesome, but scaling her proportionally would make her a giant.
It's when she lands that's the biggest problem, since she's flying normally and it makes her seem larger because of perspective. Seems finicky to pin down to adjust skillshots accordingly and such, but maybe when she lands on the ground to emote, she should scale larger or something >.>
At any rate, thanks for posting. My post kind of sounds snarky, but I don't mean it as such. I recall a Rioter posted something about how there was a long term scaling normalization down the road, so I don't mind it right now.
