I know a lot of people will laugh with this, but Kitana also needs more help. She's way too honest of a character.
Most people say that she's dumb af, but they keep getting caught mid air and by her mid. That doesn't make her broken. All of her strings have gaps, and if you're patient you can simply outplay her.
As the game has aged, she hasn't received buffs to her kit, only some minor changes to her combo routes, and new abilities.
I do think that she'd benefit from a better B1 and B3 strings, along with possibly her old flutter. I wouldn't mind the gaps and the non existent mixups (don't even care about them), but I do think that she needs to be good at what she does, and is just meh.
If Kitana was this broken as people say she is, we'd see her in tournaments, yet we see more and more of "low tier omg pls buff" sub zero, who is in every tournament, and "omg he's trash now" T-1000's than ever.
I know tournament representation isn't always indicative, but the fact that we so rarely see her says something. With kitana, you simply have to outsmart the opponent which in itself isn't viable longterm, and good against top tiers.
I also don't want to hear arguments saying that she got one million buffs each game that she's been in, which is true, but have people ever thought that she launched in a bad state in almost every game she is in? Lol
