I definitely see where you're coming from; when someone says "dwarf" or "elf," it conjures up a very specific, recognizable image. Yet, WHFB has promoted distinct different subgroups of elf (high, dark, wood) and each draws its own fans. Not to mention its brief stint with Chaos Dwarves (RIP). Different editions/campaing settings of roleplaying games have tried to make even more distinctions of classic races, though I suppose there's a reason why the traditional branches always come to mind first.

I understand what you mean, but you can just as easily look at the vast wealth of human cultures and appreciate them for being unique. Compare the Aztecs to the Celts to the Norse to the Romans to the Greeks to the Chinese to, etc. etc. Plus, when you have a fantasy setting, these can be combined and played with to create entirely new cultures. With such an array of material, what more does adding dwarves or elves even add?
