The same logic can not be applied. Clearly you did not understand my post. I have no problem with tropey characters nor sexual characters , so long as they are formed convincingly and make sense.
The mature sexual dominatrix/assassin female is almost a rite of passage in fighting games, ivy in sc, Anna in tekken, sindel in mk. Not only is Christie a homage to the genre, her design, costume and personality actually make sense. Her sexual appearance is tied into her personality and her back story. We actually see in her DOA4 ending scene that’s she disguises herself as a stripper to catch her prey. It makes make sense, it’s coherent. Her image is fit for purpose.
What doesn’t make sense is a scientist with a face and body of a 12 year old and voice of a young adult, only made 18 on paper so they don’t get banned in EUR markets once they write her to be completely oblivious of her sexuality as they put her in suggestive outfits and poses. Not coherent, not convincing, that’s not a character it’s a product for more pervy merchandising. And that’s why DOA will never be taken seriously. Next case.
