surely you don't mean to say that you would use a backdash to get in on somebody lol. If you mean HD, well the point of them is to combo obviously. What I was getting at was, there are a few characters that would benefit from being able to HD bypass using air specials/DMs FROM a backdash. I main Robert and basically any time he can juggle with EX divekick, he can also opt to HD bypass it. Here's an example I recorded a while ago (not to get off topic):
the link isn't impossibly strict, but it's difficult getting a bypassed EX divekick right off the ground since the timing is awkward if you TK it. With Kyo, in the corner if you get D upkicks, you can air EX Orochi bypass and extend the combo in HD. Backdash bypassing would make combos like these a lot easier, in my opinion.
