elaborate? specific examples help, like, i agree it is way too easy to be considered an elf but examples please
Lets use another example, horns
So for horned things, uou can basically mix and match a lot of them. Not all of them, but you can get flags for dragons or demons or whatever with different kinds of horns. And that thematically makes sense, because dragons or demons historically in mythology are amalgamation of animal parts, and/or anthropomorphized concepts/the environment around you. Ok sure you can be a dragon with bull horns fine. Or be a plant demon
But Leotherans are just... big cats. I should just be able to slap some ears and a tail on ( with normal human junk ) and still be a catfolk. Because they are just... big cats. Leotheran flags seem to be different than cat folks flags. Which already have the problem why can't I be a catfolk with normal human junk. I can be a kitsuine a race that has one of the most restrictive transformation situations with normal human junk.
I guess i get the idea, you don't want people to accidentally slip into something else just because they have the wrong horns or the wrong tail. Because if you wanna be a weird dragon or demon, this system works really well. But if you want to be , imo one of the most basic things in fantasy a, a cat boy. With normal human junk, one of the most simplest things, you just cant. Especially one with different kinds of cat parts
