I disagree with some of that:
Shes too meter reliant: This is irrelevant becuase she builds a ridiculous amount of meter anyway. She also has good offense without meter although she can't capitalize nearly as well.
Lacks safety: Not true at all. B1 2+4 is completely safe, b31 is completely safe, f2 is completely safe, most of here tele cancels are still safe(except b1 2+4
) The only string of hers that is unsafe is b2, and it's -7 which is teetering the line. I get you were probably talking about rekkas but I would like to point out that any rekka string can be made safe with a bar and EX rekkas are also safe.
Gaps everywhere: She has a lot of gaps but tbh if you condition your opponents properly you can get around them most of the time(unless they play KL).
Mixups being medium risk low reward: I don't think a combo is ever a low reward. Keep in mind I am talking about rekkas hitting and being confirmed for a full combo. Its more medium risk medium reward.
Pros:
Decent Projectile: I actually think her projectile is overrated. Ive never found it particularly useful when people realize its a mid and a lot of characters can punish her for trying to throw it carelessly.
I would also add chip damage to pros. She has at worst the 2nd best chip damage in the game(FF liu Kang may be higher). Her chip damage is absolutely ridiculous, you can still get like 50% chip damage with 3 bars(against characters that EX tonfa doesnt whiff on lol).
I dont really feel I have enough knowledge of other characters to accurately put her in a tier list, but I think she is in a good place atm. I wouldnt mind buffs to the other variations but I dont know if I would say they are needed.
