Is SA Kayn in a good spot?

Since there really aren't stats of SA winrates vs Darkin winrates, I'm not too sure. But if SA isn't in a good spot, here's a proposed mini-buff for him.

SA Kayn's Q cast range should be a bit larger when coming out of a wall. Since he's an Assassin, he should have a touch more mobility on his Q after coming out of a wall. I'm not sure how strong this buff could be but it feels awkward leaving a wall and missing your target with your Q.

I enjoy both of Kayns forms but I still feel like Darkin provides a lot more than SA. And minor adjustments to SA would be really nice.
