The bug I found is highly exploitable so I'm hesitant to put it up on a forum, but it's worth mentioning since I want it fixed at some point. I apologize if it Is already known, but I haven't heard it mentioned. The zone attack input can be used for parrying probably because the start up is a heavy. It can be abused as an option select if you don't know whether someone is attacking or feinting since it both parries the attack and interrupts the feint. It only seems to work as characters with slow zone attacks. I've confirmed it on Nobushi and Lawbringer on PS4. I suspect it works with a couple of other characters and probably Peacekeeper's hidden dagger since it operates under the same principle as zone attacks. I hope this feedback is useful. Cheers!
