4p, and the bt round house, her zoning is safe which i don't believe she deserves because she also has a strong rushdown
Ayane does not play "rushdown". She has decent speeds with the 10i jab, 13i mid, & then a 12i low, but in no way does her speeds or tools (in general) emphasize rush down. She does have good damage output & have great mobility, however but her rushdown isn't strong to say that. Getting in, she 66KK4 & BT PP6KK4 are noticable. Other than that, she's baiting you with her 1P+K & 33 movement with a rolling throw, kick, or jump.
PP6P3, 6P3, 33 in general is made to evade your highs & mids when you're on the offensive. When she uses these 6P3 enders, she's trying to get you to hit attack buttons so that she can score a counter hit, most likely launching afterwards. If not, then she's grabbing you; this is on you to pick up on the scheme & then strike when she tries to grab. Ayane is a very defensive character. She's a character who takes advantage of opponents' mistakes, besides zoning. She's made to do that as well as use tools to play keep away (3H+K > 8P, P>BT8P, P4P, etc). It's a part of her general strategy to bait you out.
4P is supposed to crush. It's also unsafe on block. It possess crush properties to crush jabs. If you're throwing out a high & if she gets a reads, then it's because she's making a good read on you. BT 4H+K is unsafe on block. You can punish it. You have to be careful getting in on her or you'll run into it. The stuff that you're wanting nerfed are a part of her general gameplan overall.
She's a character that is just fine, just that she forces you to make good reads both with & against her. Overall, she's making you play smart.
