[GAMEPLAY] Kayn has no inking around his model.
Whether or not you toggle Character Inking on/off in Settings>Video>Character Inking in client, a dark outline does not appear on Kayn. I think this makes him look kind of wonky in comparison to every other champion who has it, when you have it toggled on.

For a comparison, here's Aatrox with Character Inking turned on and off. If you are having a hard time seeing it, note the dark outline around his blade in one picture, and the absence of it in another:

Note the differences between the two. I hope this gets resolved soon!
