YES, and Ayane's BT7K turning into 7K -_- on angled juggles in corners (with that said, could Ayane's 7K be i13 or i14 instead of frickin' i18? The move is -30 on block so you can't exactly spam it anyway)
Because Ayane's worst MU's are even and she has the advantage over half the roster. This isn't an Ayane vs Hayate MU thing, it's an Ayane vs the roster and Hayate vs the roster thing.
