I still feel like kitana is one of the worst matchups for scorpion because she wins from every area on the screen. Add cyrax to that too. Cage and sonya are bad but at least scorpion can use his hellfire in those matches.
Sonya and cage should only be trying to get in the whole time. Sonya has a great projectile but imo it's no good against scorpion and a well times d3 stuffs sonya's d4.
Kitana may not be able to do the same chip as those characters but her footsies are insanely better than scorpions and d4 is not enough to deal with them imo. She doesn't have to come in at him at all, the runaway game works insanely well if she gets a life lead because scorpion can't do anything but take a huge risk to stop it. She is also building free meter while you close the gap. If you do close the gap and corner her square wave will get her killed but instead of doing that she can just space you out, it's really not too bad of a spot for kitana, especially with meter.
