Believe me, I know how important a tool YL's Nair. That's why I said to keep all of its properties. It'd still be the exact same move, just that it wouldn't look bad. And I'm not just talking about that picture, I've seen it in the streams, and regardless of how many tweaks are made to the animation, I doubt TL kicking can ever look good.
To the claims that it doesn't look bad: I realize that appearance is entirely subjective, that's why I presented less-subjective justifications for a sex stab. I wouldn't go so far as to say a minor improvement to priority and a canonical reference are good in an objective sense (some might feel that TL's already overpowered as it is or that AoL is a game best forgotten), but they're more substantial than aesthetics alone, and I would say they are aligned with the project goals.
What would be the most reasonable counterargument against my stance – disinterest on the part of the animators themselves – has never even been hinted at; and considering all the other amazing changes already made (many of which also have no mechanical impact), and even the creation of the TL sex kick itself, I'm still hesitant to conclude that that's the case.
So then what is holding it back? Some say it looks okay as is, but I imagine they'd say it would look okay as it could be, and I'm not the first to say it does not look okay… It'd have no negative effect on YL gameplay, and not even any more neutral effects than there are currently considering TL's hurtboxes are already insubstantially different from YL's simply by nature of having different proportions, so that angle's been covered…
