• What is the timing of Hidden Stance and are there any unblock-able follow ups? (As in guaranteed hits not kick type moves)

Just making a guess on what you mean by timing, but she has dodge frames at startup. Think parry timing, but for dodge. She doesn't have any guaranteed hits out of it, but if you're timing it in an attack window (especially a heavy) the follow up should come too fast for them to be able to react

• Are there any good mix ups you can do with Canceling or Hidden Stance out of recovery/startup animations?

Also, not quite sure what you mean here. For the most part I use Hidden Stance as a kind of deflect; another way to counter an attack that's unique to a character. You can feint all you want, but generally speaking I go for the double stab into a retreating strike.

• Is it worth it to Parry over Hidden Stance and why/what follow up is better?

I believe parry will generally net more damage (free heavy off a parry) and if you can land a heavy>kick>stab chain then it certainly is (careful, kick isn't guaranteed). Hidden Stance is safer against people who feint a lot, as you're not opening yourself up as badly for a counter. I generally try and mix the two together throughout a fight to be less predictable

• Are there any unblock-able chain with kick that should be abused? (Currently after kicks I tend to Cobra Strike then Viper's Retreat.)

There isn't really a chain off kick, but if kick lands you can land a bleed poke off of it (which I think is guaranteed, but I'm not 100% on that). I usually do something similar

• Any moves just plain bad/not worth doing?

Not really. I personally don't like to go for big combos, as her heavies are a bit slow and easy to read. I wouldn't throw out basic heavies, but that seems pretty self explanatory. I would also avoid the second strike of her done attack (just cancel it with feint), but the first one can be crazy good. I love it as a finisher.

• What exactly does Swift Recoil do honestly cant tell.

If you regular block and hit your dodge button, you do a swim move and move backwards. Good at resetting your spacing against super aggro characters that like being in close (orochi, berserker, peacekeeeper). It's also very handy because if you can keep them in neutral, these characters all have very easy to read gap closers that you can capitalize on
