I just disregarded BDACUS when it was first discovered because it seemed pretty useless to me
But Falco isn't tall enough to force an air release on any character really without slopes, right?
you are a smart smart man, BDACUS has no real improvement on Falco's DACUS, it goes about a body length further (which is probably ~10% of DACUS distance) and comes out at the same speed ignoring the 1 frame buffer advantage of the Usmash canceling the DA
And no, he can't release anybody without a slope (except maybe squirtle, I remember somebody arguing with me once)
I've also heard from a reliable source before (I forget who, but it may have been Ankoku) that you can't buffer anything out of a grab release, therefore you can't bDACUS out of a grab release, you're probably just using DACUS, I mean like i said before, you would never know which one you're using without a side-by-side comparison
Of course I've always wondered why "pros" would never try and "bait" an air release from an opponent into a DACUS at kill percents, it's not that hard, just pummel until they start mashing, worst case scenario they don't mash and you can pummel them like 8 times (at kill percents)
I'd like to take back saying bDACUS is completely useless, the cross-up would be nice in case they shield it.
