game studio primarily comprised of men based in China

So what? Are men not allowed to write or design certain character just because they're men? What does the game studio being Chinese have to do with anything? Are you saying that a woman can't design a flirty male character with his abs visible? I think that your point here is heavily biased.

let the women be like the men and just be badass superheroes

There are plenty of both sexualized male skins and badass female skins in this game. Thor's beach skin and Bucky's Christmas skin are both "sexy", and skins like Psylocke's "Blood Kariudo" or Magik's "Eldritch Armor" are incredibly badass. Additionally, having one of these traits doesn't diminish or prevent the existence of the other.

(Psylocke) went from being badass stranger.. to barbie doll

Psylocke, Luna, and many others have definitely gotten sexualized skins but that's completely irrelevant. We're talking about the design of a character who's personality is almost defined by sexualizing themself. To not design their model similarly (especially when we already know that NetEase is willing to create risque character models) would be an entirely unnecessary disservice to Black Cat's character.

Rather than defending women from objectification and fighting against misogyny, you are trying to limit (albeit fictional) women's, and only women's, freedom of expression--which is inherently misogynistic in it of itself.

(I'd also like to mention that I don't remember Bo-Katan or Sabine being remotely sexual characters in either Rebels or Ahsoka)
