I do wonder if this will be considered. LOTR movies imprinted a new elf image in people's minds. I mean, even elves in Tolkien's world were not supposed to be humans with pointed ears, but after the movies...
I bet Larian didn't even give it much thought. The general public now views elves like this, and it is easier to implement, so...
I say this because until reading this and other posts about elves and drow, I didn't even think about it. I remember seeing the first guy elf model and even thinking, "Ah. I can be Legolas."
Also, thinking back to other video games and such for D&D, I don't think there is much of a difference in those games either between humans and elves.
I'm not saying they shouldn't do something about this. Im just saying that for most people, it will probably go unnoticed. In fact, many non-D&D players might even freak out if elves don't look like humans with pointy ears. You know. "What the crap! Why do all elves look so weird? I wanted to make an elf character who looks like Legolas, not something closer to a Christmas elf."
