I definitely agree about the faster poke. In a game with cancelable specials, it's crazy that everyone doesn't have a quick enough "get off me" move already. Interestingly enough, I'd say that Unbreakable currently has it the best in this department out of the three Sub variations, since he can use his 6 frame Parry to cover this need.
As for the rest:
1) Being able to Parry jump-ins would be definitely be nice, but to make it fair, they'd have to do the same for all other characters with Parry. That's a lot to change and I doubt they will. If anything, I'd hope that they would normalize what can be Parried. For example, why can I Parry one characters Teleport special but not another? This should be the same across the board for all Parries.
2) 6 frames for the regular is fine IMO, as virtually nothing in this game is faster than 6 frames (except some Parries). However, I do agree that his EN Parry should be faster so that it can interrupt gaps in strings like armored moves. The fact that it can't makes it currently pretty pointless.
3) You make the best argument I've heard for why Parry should recover instantly from projectiles (i.e. to help his meter build game), but there are advantages to its current design. Namely, when being rushed down by Kung Lao, who has an Orbiting Hat going, it's great that it doesn't go away, as it stops the Hat and whatever limb KL throws out. Also, since Aura negates chip we don't really need another way to deal with projectiles. So, to me, it's fine as is.
What I'd really like to see, as some other have also mentioned, is a better neutral string for both Unbreakable and Cyro, so they can play better footsies. Beyond that Aura should make him immune to DOT effects. The fact that it doesn't is crazy to me. Unbreakable should be Sub's answer for Acidic! And it would be nice if a few other moves could be canceled into Aura and continue the combo besides only B12. Come on, F4 at the least should work.
Otherwise, I think he's good as is. Fingers crossed they do some of the above.
