I'm unconvinced that a slow (perhaps even stepable) high horizontal is a good addition to a stance. Note, how much of that description fits the SC4 version of SRSH A. I hope Synraii can shed some light on the matter when he attends the mess in London.
Other observations from the videos:
- the new horizontal that looks like the 2nd hit of SC4 66KA appears to have a TC
- the new hilt stab move causes a fall down stun on counterhit, doesn't appear to guarantee anything, tho
- pushback on BBK on block is immense, the kick also appears to be mid
- the new 4BK looks both faster and guaranteed on normal hit, still has very little range, but might actually be useful as a punisher
- 3B into BE combos are still fucking boss
