Reason I don't like it is because its not something you'll use in like every fight. It would be awesome if her back turned parries can parry moves after someone does an OH and puts you in a situation where your back is turned. For example, Rachel's grab where she goes over you and your back is turned and then she'll do a mid kick or mid punch.
false. her back turned parries are awesome. And yes, you can parry those moves from Rachel. I do that all the time as Bayman. Also works on christie's throw. There are some back turned situations that you cannot parry out of due to disadvantage.
You'll for sure use other moves more than others in your move list, but every move has a purpose.
Make sure on your input that you're hitting the right direction. Otherwise your character has to turn around first to parry rather than it being instant.
How many frames is Batman's back turned parry? Every time I do it online it never goes though. It could be one of those online moments where people can get away with it.
