Here are my thoughts on it, all personal opinions
Freddy - obviously outzoned in this matchup, and any mistake when trying to get in can eat a ground spike and send you back fullscreen. nightmare stance nullifies all wakeup attempts by kitana and he can otherwise compete up close with her. 3-7
Kabal - iagb's are an obvious issue which typically gives him enough meter for a breaker by the time you close in on him. however, when kitana pushes him to the corner she can start playing her game on him and capitalize on his mistakes better than most others. 4-6
Cyrax - i've stated a lot about this matchup already, which i think is 5-5. kitana gets the zoning advantage, but properly spaced d4's by him prevent a normal footsies game and his touch of death factor makes him scary up close, where he gets a slight advantage. Cyblax I think is slightly better for him but not enough for a full number change imo, i just think it's worth a discussion.If I were to use decimals I would put this as maybe 5.5-4.5 vs robot and 5-5 vs human.
Cage - another case where kitana zones him out, but once he makes it in he prevents kitana from making any kind of mistake. her lack of an armored move is a problem here and d1'ing out of pressure can be risky with the f3 punish on block. 5-5
Liu Kang - Kitana gets outzoned here, which is the first problem. b3 can punish d1's and he wins up close in general. his advancing strings make jumping out of pressure an issue as well. fortunately though, he isn't so bad that you can't play footsies with him. 4-6
Ermac - I've been told that this is my own personal problem with the matchup, but I just don't see that. Ermac is just like Kenshi but sacrificing some of the better keep-away and lack of armor for better damage. This makes it a little easier than Kenshi, but still bad imo. 4-6
Mileena - Though this used to be considered in Mileena's favor, I don't think it's that way anymore. Mileena keeps Kitana out a little bit, but Kitana has better normals, better damage, and forces Mileena to take risks which us Kitana players love. 6-4
Sonya - While I think this MIGHT be 5-5 on a larger stage since you can lame it out more easily, Sonya's d4 ms is stupid in this matchup and a good Sonya player can kill anything Kitana tries up close. 4-6
Skarlet - Skarlet keeps Kitana out here, but it's not as scary as others. What Kitana gets here is the fear of the Skarlet player to take risks. Any time they decide to go for the overhead, they are putting half of their healthbar on the line, and their only option becomes sliding all day. It's somewhat similar to Mileena in this regard because she's forced to take occasional risks to get things done. 6-4
I don't see how Jax would be in his favor. Care to elaborate on it?
