I'm not a huge fan of the parry so far but I think it will have its uses here and there. Definitely hugely risky without yrc ready, probably inadvisable in those situations.
Worth noting that if you're looking to create space, ground strings ending in 2D can be followed up with 236P for the slowdown effect, allowing you to back off with more safety.
Definitely seems to have potential ad a character, though I'm not sure his offensive options are oppressive enough to put him in top tier. Need to see how most of the cast deals with his zoning potential, as it's pretty strong and varied from what I can tell so far.
