Disclaimer: I know today is the official release of ShB however, having played around with the new Ninja toolkit and tried the suggested openers, there's a single thing that makes the least sense to me: Why is Hyoton not a 1-step upgrade from Fuma?
Ninja has avoided clipping GCDs in openers/rotations due to Fuma being worth more than Raiton in single-target situations. But now our dripping blades and slashing resistances are gone, Raiton/Hyosho are much better. 2-step mudras clip unless you live inside the internet and during a rotation I can handle doing Raiton due to the nature of the skill and the fact if fits class fantasy quite well. But Hyosho being an upgrade of Fuma fits the animation more than Hyoton and it would allow the class to flow better in single-target situations/fights.
I can understand why they made Hyosho a 2-step, considering Hyoton was a completely useless skill at max level+ and they want to make sure every button is pressed at least once. Personally though it comes at the cost of a skill that could easily feel much better to use while not hindering class fantasy.
