About fisticuffs, imo the only thing he needs now (besides speedbag whiffing issues being solved, which I doubt it ever happens) is getting exflipkick armored again, and maybe safe, why not.
This move would prevent him from being free on the ground and would also help antiairing and anticrossuping as before. Nothing else.
He's never going to be a great character having no true mixups in this crazy game, keeping that punishable d3, or his fastest starter being 9f (slow for a character that is supposed to be rushdown and pressure...), etc, but he will be able to play his honest game better, not being free when he gets knocked down.
For stunt double, mimic kick should combo in the corner again. That going away made no sense. Also, mimic kick could be a bit more than +2...not double digits plus as before, but like, +4/5?
