Another poster mentioned gold/shield dwarves. Another important distinction. Since Gold Dwarves hail from distant South-Eastern Faerun, and would have a very different perspective. "Where I'm from, drow ride horses and worship Loviatar". "Chosen of Mystra? I saw far more impressive wizards than you in Halruaa, Gale"
Well, to be fair, the change with the dwarves is more cosmetic than with elves, because shield dwarves are also known as mountain dwarves and gold dwarves are also known as hill dwarves, so it's just taking off a bit of flavour. Elves are a much more drastic change, because both sun and moon elves are dumped into one subrace (high elves) and as you mentioned, the distinction is culturally important.
