It's not a useless move, but you can just 2A and block to bait > Punish, so just remember it's not a DP. Your opponent doesn't have to treat it like a DP, at least on your wake up.
I usually only get real use out of the move against Valk wolf strings, though. Or a Ragna trying to do gauntlet hades or something in their strings.
How do I say this....It's a bad counter, but it's something, I guess. It's something to use when you know there's a gap you normally wouldn't be able to mash/jump out of and you're somewhat sure they're going to do something with a lot of recovery frames. Case in point, Ragna 5B > 5C > Gauntlet Hades.
