Just a little quick fact as to why this works. Not that it affects the technique in anyway, but just felt like pointing out why (if it's already been pointed out, I missed it. I'm to bloody lazy to read EVERYthing XD)
Wolf's Dash is angled, right? Well, the reason he is able to pull this technique off is because of this (as all of you already know). But I went to training and slowed down the playtime to the slowest, and I found something (probably not the first one, but I'm just stating). He doesn't go THROUGH the stage, he goes over the ledge. He just goes at such a speed that makes it seem like it's going through it. So it's not really abusing the game or glitching it, it's just something that happens to work. Because of this, there could be a way to negate this 'Scarring' if the opponent is quick enough.
Just thought I'd point that out to anyone who wants to work against this. A friend and I have tried this, and it's possible to counter if you're quick enough.
