Going through more while a dev call is happening:
Reverse fAir: HYESZ
Slow Illusion Hitbox: It does, we'll fix it
Lasers: Fox does not any hitstun on his lasers ever, especially since they're cancelable into anything, AND cancel into jump and then shoot another laser
Shine requests: It's already jump cancelable, so this change isn't really significant enough to seem necessary
Gandouken: Gandouken will be fixed and improved.
Reflect: If it were possible to just reflect the Gandouken, we could, but we can't without making it a general reflector.
Chaingrabs: We're not going to return free infinite handoffs but we'll experiment. No promises however.
Quick Draw JC: That'd make him really overpowered with the momentum conservation into jumping and attacking.
Blue Fire: This has been planned forever, so yeah
8 Jumps: We'll put some research into this
dTilt: Is there a difference between Melee and Minus?
Tap/Hold Window: Most moves have a 6/7 frame window, but uAir is hard unless you're using c Stick. Most moves have a clear window though.
uAir Tail Spike: Sounds good
Quick Attack Jump Cancel: This could be a little cool but it may also be super broken so for now a cautionary no.
Quicker Moves out of UpB: Sounds like a potentially cool tech, we'll look into it
Jab IASA: Sure I suppose
Super Wave Dash: This seems like a lot more trouble than what it's worth if we even knew how to go about it
Metroid can crawl: We'll look into it
