Half Baked Elves

Elves I've never been a fan of elves in games. Or in fiction for that matter. They usually are presented as humans-but-better, including aping human civilization (but in tree houses!) and being biologically similar enough to humans to interbreed and create half-elves which are even more of the humans-but-better. Why play a human when you can play an elf or half-elf? Why aren't there half-dwarves
