Her armor is not active on the first frames, so on read you will just hit her out of catdash before she even gets a chance to meter burn it. If she meter burns through it, you better hold back and hope you don't get caught. But you will.I'm quite sure the two-hits will knock her out of catdash if she tries to armor through a gunshot and you MB'd. Is this not correct? I'm not talking about on reaction, I'm talking about expecting a catdash and MBing. Catwoman might be hestitant to catdash through Harley's guns because of the threat of a MB. Without that threat, Harley can't really zone Catwoman.
Unless I'm missing something that you could explain.
