No no no, I don't mean by exploiting the massive hitbox it had, I mean it actually invulns through it now, it never used to do that.
If I tried to catch the recovery frames of j.2C with 4D, I would always get hit by j.2C, it was one of those air moves that 4D just wouldn't work like that on. Sure if we did it super early we could hit you out of the sky with it, but it didn't lead to nearly as much.
Basically, CSX 4D is so godlike even I have to admit it's pretty fucking stupid lol
