I'm not talking about fdc, I'm referring to the ability to whiff j.2k right in yr opponent's face without hitting them. Being able to fdc earlier is the implied buff, whereas j.2k hitbox coming out sooner/lower is the implied nerf. that's exactly what I'm trying to figure out. It's translated strange to me, because as it stands, it doesn't seem like it would be possible to make j.2k come out any lower. I thought the slower timing of fdc from xx lies in the window you can cancel the animation into fd rather than the height that the move comes out.
edit:
I'm thinking it's exactly what keeponrockin said where it's actually a hitbox change. It seems as though there's no hitbox whatsoever when you're really close to the ground. I don't know if it's a proximity thing or what, but changing this would be a nerf to his mixup (whiffing j.2K at close range) and a buff to its overall use (no longer being low-profiled by stun dipper etc.) I think that makes more sense than what people are saying about it just being a change to fdc timing.
