One way races are sometimes justified in D&D is by a mechanical function, a role they play in the game as a whole. Dwarves make great fighters and halflings make great rogues. So the gnome was meant to be a good race for playing wizards and illusionists. Kind of stepping on elven toes a bit but sure. The result in lore ended up looking like a weird hybrid of details from elves, dwarves, and halflings. Fey but earth-y. Big beards and big into mining. Intrinsically magical. Borrowed a lot of the same inspiration that Tolkien used for Hobbits. Really just lacking in a unique identity. Most of the early attempts to give them something of their own was just “zany” stuff, which leaves a bad taste for many people. As time has gone on, they’ve been given a bit more to do with alchemy and steampunk engineering and stuff like that. I dig it, but for some people that still isn’t enough.
