That sounds cool, but I get the feeling combo gravity will make that sort of combo impossible. I wanna say that both will cost meter to launch, but the one used on Kotal will be a variation-specific Roll that has different hit properties. Maybe it's an overhead instead of a mid, which would be insane. I
want Roll to launch meterlessly, but MK11 has been hella stingy with meterless launchers.
Now something else that caught my attention in that same video were the possible interactions between her projectiles and reflects/absorbs discussed at around 10:33. He used her meterless ground Sai as an example, but I'm not sure if those will count as two separate hits, but it looks like her meterless Air Sai definitely will.
Now, if Instant Air Sais are viable, that could potentially make projectile absorbs useless against her. Combine that with Low Sai, and it'll be like Piercing zoning never left. And that makes me indescribably excited.
