I think it's really difficult to stray from the typical female designs in gacha games because the primary spending audience has so much sway. I watched a Moon Channel video about it and unless you hit critical mass popularity like Genshin, it's safer to capitulate to their demands else the impact to profit is too extreme.Currently taking the Wuthering Waves plunge and... the character designs have the same issues the rest of the game has when it comes to trying to compete with Genshin versus what that actually means and how they succeed.
There's always room for improvement and Genshin's character designs certainly have that. WuWa's character models are definitely more detailed, but what would have been great to see is more diversity with body shapes, outfit silhouettes and styles the characters represent. Instead, the characters are even more blatantly color-coded in accordance with their personality, not just their elements and the female characters especially have the same general silhouette for all of their outfits.
I get very little personality from their designs as any uniqueness is held back by the developers' decisions to pander to a specific audience the same way and this also extends to your interactions with them in unfortunate ways. Do they really think the way to beat Genshin is by having every single female character be thoroughly invested in the male character and more jiggle physics?
It's just been a really unfortunate experience so far. I won't say I don't welcome appealing character designs, but I feel like the character designs show so much disdain for what there is to like about female characters in general.
