You guys are acting like I would wakeup DP every time. It's the fact that you're saying it's such a bad option just because it isn't safe. Good players take risks because they think their opponent is going to do something all of the time. DPs are one of the best ways of stuffing almost any button even if they are unsafe.
And please, list every way you can make a DP whiff other than just spacing out or using a backdash (which Inferno Divider can catch several of them). And if you space a DP out, then most likely that person won't DP unless they think you're going to press a button.
Just the fact he has a good DP is enough for you to play around it, but this now also makes you . How isn't it good now?
Now about the Ragna who that other guy was playing that would mash DP on wakeup all of the time. That is bad since it's so predictable, but don't go saying "Doing wakeup inferno divider without 50% to RC is retarded" Because it's a pretty viable option. Just one you should use less than blocking. It's keeping your opponent honest.
