Ahh, the random invoking of Tolkien. It’s like invoking a fantasy Jesus who smokes a pipe.
Forgotten Realms' elves owe a lot of their aesthetics to artwork on LotR, and that's a fact. So I thought it might be a good idea to point out the original inspiration for modern fantasy elves - like it or not, it's revelant.
And in BG3 some elves could pass as humans, sure. Others are different enough with their green/golden skin. Even though I'm more of a dwarf fan, I never looked at BG3 elves as boring.
