Imo, she's been nerfed heaps. I haven't played extensively, so correct me if I'm wrong, but these are some things I've noticed:
On fastest slow escape, her new 66kk doesn't guarantee anything, and the old one causes the new bound that only guarantees very little damage, whereas in doa5 it guaranteed a CB.
The stun time on her 66p on a backturned opponent is extremely short now. h+k doesn't BT now (I don't get why they'd take it off her and just give it to Momiji and Hayate), but it does BT while the opponent's in stun.
The second kick of 9kk and all it's other forms in strings can be tech rolled out of.
Also, her new ender with 9pk and kk out of hoshinpo does more dmg (and it's pretty minimal at that) the 9pk has a big pushback into a wall (just something I've experienced a lot), so I'll probably just stick to her old ender.
What do you guys think?
