100% agree!
My emotional response is that Gachas are a sick plight on the world and should be eradicated like any disease.
My business response is yes, the need to have their own category for the simplereason they clog up the categories genuine creators and merchants use to sell their wares. An analogy would be a designer running a RL store and having someone set up a flea market inside your store selling similiar cheap items imported from some 3rd world country.
Genuine merchants, by this I mean individuals who spend time, money, and thought in creating actually contribute to the SL world with new items, full outfits, and full builds. Gacha sellers to me are no better than carnys flogging the stuffed toy from their games to the general public. .
