She makes nw fear j2 because if he does a preemptive j2 and she crouches its full combo punish. She can easily forward dash to make ground pound whiff. Even if u block catdash full screen u cant punish and nows shes up close to you exactly where she wants to be. If u do a ground pound and she does j2 it full combo punishes nw. Off of a j2 if nw anti airs he doesnt get nearly as much damage as catwoman gets fromt a whiffed ground pound and then she gets a 50/50 after that knockdown into even more damage. NW outfootsies but a lot of his stuff whiffs on her wakeup flip kick whiffs for a full punish where as all nw gets by punishing her wakeups is staff spin
If she's crouching looking for a jump 2 then it's your cue to continue ground pound or go in with standing 2. This is screen control. Just because she has an option to get past the zoning doesn't mean it isn't good. Everything can be jumped or ducked or something. The point is she has to make the read and he gets to play his game because of it.
If you block a Cat Dash full screen you can't punish it but she's still negative. She isn't "in where she wants to be". Quite the opposite, you get your offense going.
She doesn't get a free 50/50 if you knock NW down. While his wakeup attacks are not fully invincible he can vary the timing with delayed wakeup so that she cannot stuff all of them with her 50/50. On the other hand Nightwing actually can if she doesn't have trait.
The important moves we're talking about don't whiff.
Who says Nightwing only gets a staff spin for punishing her wakeups? Cat Dash and Cat Claws have poor invincibility. You can just straight up do whatever you want. You should be stuffing her wakeups with standing 2 or Ground Pound.
