Not to down play, but I'm pretty sure we've known this tech for a while. And considering we can get around the same amount of damage for a bar, it's definitely a waste. Still, props for finding it out yourself. P.S, in this variation, we can do b2>f12b2 for more damage, and it hits much more consistently.
Resets aren't guaranteed unfortunately:/ It'd be like looking at Shinnok saying "wow Imposter has 90% corner combos." Having said that I get what you're saying! I don't really like his pokes and air game.
