I don't agree with this, as it undermines that there are a set of feminie qualities, which do exist and should be celebrated and used.
Let's have an example in Tress Merigold in TW3. There's a part of the game when she must attend a costume party and invites Gerald, she really enjoys teasing him, telling him to use elegant clothes and act "like a gentleman". She gets drunk at the party, and starts acting flirty to Gerald, which culminates in a kiss (well, if you choose to). When she sobers up she apologizes and says she shouldn't have done that, to which Gerald says she doesn't have to. She parts ways with him with bittersweetness on her eyes.
There are clearly feminine archetypes going on there, she's the "romantic", she's "flirty" and she's "thoughtful about physical contact", but that doesn't maen she's not a goddamned badass witch that doesn't think twice to kill every man on her path. She's sweet yet strong (Which is a contrast to Yeneffer, who is rough but soft on the inside).
If a writer just writes a man and then swaps his gender to create an "stronger charcter", he would miss some sensibilites that make for a real, strong female character. Otherwise you end uop with the "badass woman" archetype, as there are very few instances of a male character being written well, let alone with actual heart or sensibilities.
The thing there, and what a lot of writing - for male and female characters alike - fails to consider, is that behaviour
is partially dependent on context. More broadly it's being at a party and all, but in the specific context of the game, it's a
party and the first time in a long while where she's been able to relax without worrying that Witch Hunters aren't about to try and kill her. For the vast bulk of players who haven't played the previous games and thus don't know Triss so well, it's a chance to see another side of her that's... just, well, another side of her. It doesn't compromise her abilities or require that some other aspect of her character be altered - another game might require her humbling by a third party - to reveal this more open and fun-loving side, only that she be in the right circumstances to reveal it.
This is one of my main frustrations with alt-costumes in fighting games, because nominally they're a perfect way of integrating this sort of thing into a genre that's otherwise pretty minimal on characterisation. As it is, fighting game character designs often struggle where their default costumes must be all in one archetypes that tell you
everything about the character at once, while alts ultimately change nothing about their mannerisms and personality and thus reveal nothing new. Chun-Li in Street Fighter V is most indicative of the potential and how it isn't especially used, I think.
In the base game she has three costumes: Her default, most famous outfit with the blue dress, tights, and hair buns. Then she has a story mode outfit which compromises a police uniform, reflecting the fact that she's actually an office of the law. Lastly there is her pre-order bonus, a more revealing black dress where she lets her hair down. Now thing is, people seemed pretty fond of the latter when it was revealed even though it was a modification of an existing alt from Street Fighter IV, and I think it's because for her - in light of her default costume and the police uniform - it
did come across as another side to the character. It's not what Chun-Li deliberately wears to a fight, it's what she wears to a fancy dinner; when she both literally and proverbially lets her hair down. On the other hand, her behaviour between the costumes doesn't change at all, so while it provides a visual indication of some depth to Chun-Li's character, there's little substance beyond that. At least she's lucky enough to have her costumes divided into clearly separate roles - a lot of the women in the franchise, nevermind the wider genre, just have some variant of the same theme while also having a common thread of 'sexy'.
