Yatsu doesn't have bad reflexes, he's just horribly heavy. Gigantic sword, lots of armor, 7 foot tall muscle-bound frame [muscle is heavier than fat, which would be seen with Port]. If you recall, he was the one that reacted to Mercury's incoming attack during the doubles match first by sensing it coming, then pushing Coco to the side [this however does prove your point about Aura sense and such]. And then held up against that guy for awhile, and Mercury's got beyond insane reflexes. Sage, point taken. He's probably a badass fighter, but he too is slow. Unlike Yatsu, he is a 1st year, so he never got a chance to shine [least not yet].

But yeah, fast reflexes are to be expected. Still, that isn't to say that his Semblance isn't some [enhanced] or slightly different application to the technique. Honestly,we can't say until we hear confirmation from the writers or producers, and they have a nasty habit of deceiving us and withholding things from the viewers. So....
