I know the game has been around for a while. I'm a day 1 player but I haven't seen any WuWa fanarts here in the site :(

First things first: You can try and change that.

But I understand the struggle: there are just so many gachas out there: Arknights, anything from MiHoYo, Blue Archive, Fate/Grand Order, Girl's Frontline, Reverse:1999, Human Race-Horses Managment Simulator, Path to Nowhere, Azur Lane ... just to name a few. I kind of understand the uploaders have to balance this against "proper" yuri

You're not the first voice to call out for some underrepresented gacha yuri either. (Don't ask me how long it took for even a single PGR post to get here.)
