It was pretty bad in Extend. I don't think I was actually hit by it, despite multiple Hakumen trying it out extensively. It doesn't help that at that range, Tsubaki is unsafe (unless the Hakumen weren't pressing buttons fast enough) and you can actually stuff late air attacks from Hakumen at that range pretty easily (if you are using a character with a good AA 5A). It might be more legit in CP, since Agito will make them afraid of pressing buttons against Hakumen but reacting and blocking the Tsubaki still shouldn't be that tough.
