As a Swede, I am hardly unbiased on the issue. Scandinavian history, folklore, and mythology hardly ever gets any serious representation (just look at what they've done to my beautiful trolls) and is often regarded with contempt, ridicule, and looked down the nose on (see anything that includes "Vikings"). Anything that makes elves more generic than they already are will make me feel sad about it.
And I'm not saying DnD elves aren't already genericified to hell. They are, and I dislike that. So yeah, I basically balance back and fro between being sad about that and this opinion:
