Fimir, giant cyclopean lizard-things with clubbed tails, in a world where GW just released vampires, skeletons and zombies in an edition where the main villains were ghosts and our big faction releases have included trolls and goblins isn't holding up imo.
If anything, AOS thrives as a world with generic fantasy (blackpowder pistols, dragons, vampires, goblins) and absolutely bonkers fantasy (soul stealing shark-riding elves, giant cow mountain elementals, the entire skaven faction, lightning-riding immortal demigods)
