I'm speaking for Assassin in this post.
Ninjutsu is all about the foosties. F2 and B2 mainly. Kitana punishes f2 with throat slice. It's only safe when spaced properly, but even then, I get a d1 check. And even if that's not enough, parry checks it just fine. That alone makes it scary to throw it out. B2 gets bopped and Kitana hits hard, especially in this variation. Mixing up iAfs with parry makes it hard for the scorpion to teleport, and again, Kitana hits hard in this variation. Assassin strike is a good move to use in the neutral after mixing it up with runs because there's no way you're reacting to the difference. If it hits, you're right in my face and I get to activate sharpen. Scorpions love meeting players in the air and Kitana is the wrong player to do that against, especially since my j2 is faster than your jump ins.
Don't get me wrong. Not at all saying Kitana wins. Just saying she is perfectly fine in the MU. We still have to deal with your annoying d4. Teleport will always be a threat, even with our options against it. The low starter (b3?) is a perfect answer to parry. You hit just as hard meterlessly as we do.
Blake and KP just played a set yesterday and KP won that convincingly. Watch it if you get the chance
