Great list overall. I agree with almost everything. I am surprised Jax isn't higher, but some people here pointed out a few flaws I was unaware of. Also, curious why people think Reptile is so low?
I do find it a bit ironic that that Kitana, while being bottom tier without a doubt, has favorable matches against some of the upper tiered characters. Kung Jin being the most brought up example, even though I think more Jin players should be looking into Ancestral. Then characters like Mileena or hell, even Goro give Kitana a lot of trouble. I think if she didn't fare well against some of these upper tiered characters, people would be saying she is D tier.
She needs help, obviously. Her zoning is easily the worst of all the "zoning" type characters. The threat of her zoning is moot once people start ducking fans and inching forward, something the entire cast can do. Mournful glaives hitting mid is nice, but the damage is terrible and leads to nothing. Air glaives are a joke and can be punished a good distance away.
Up close, Kitana is basically useless. She has no mix-ups, no pressure, no safe strings aside from 111 and b12 (both of which have terrible range), no safe quick pokes, float gimmicks that can be D2'ed once people start realizing it, and her only overhead is so slow and unsafe with crap damage that only leads to HKD. You can literally crouch block everything she does except for her x-ray, which she will never get to use because she has to blow meter on YOLO armored wakeups when people get in. You can shut her down completely by doing nothing but quick, safe strings and pokes because all her strings come out too slow and or are - on block. Her meterless damage output means nothing if she can't actually get it in outside of people making stupid mistakes.
I feel she needs buffs, but not to the extent some of the Kitana community thinks. I don't think f2 being an overhead is the answer. I don't think fans hitting mid is the answer either. Make D1 a good poke again like MK9 by making it 8 frames of startup and not -10 (seriously, why is this -10?) on block, make B2 faster so people have to respect it and not crouch block all day, and make some of her forward advancing strings like F112 or F22 safe on block. That's it.
She also needs some of her useless specials looked into. Players shouldn't be able to block successful parries. Reflect should at least be as good as Kenshi's by having faster startup. EX air glaive should have a reason to be used, because clearly there isn't one. Non-Royal Storm EX fan lift should have armor rather than deal, what, 3%? 5%? damage and screw up optimal followup combos.
Just my thoughts. Also I think a variation tier list would be more accurate in theory, but making one based on matchups when some are seldomly used (see Ancestral above) it would be almost impossible to do.
