They cut it for me.
Personally, I don't get this idea that only a +1 Dexterity over humans is enough to make them nonhuman, when, as
@Hussar has pointed out many times, they are practically immortal, innately magical gender-fluid beings that never sleep and relive their past lives every night.
Sure, I get it, "we never see that in gameplay" but we see them being half an ASI better and Dex and suddenly they are bizarre aliens completely unrelated to humans?
There are a lot of things we can do with traits, feats, culture, tradition, language. Good Lord, think about what we could do with just the idea that the Elven language doesn't have a word for death? That their word for dying is closer to the idea of "passing through town". Go back and instead of saying that Planetars serve all gods, make some unique elven Celestials, who are the guardians who watch over their people. There are hundreds of things we could do to make them unique without having to try and shoe-horn in a +2.5% advantage over humans in dexterity checks.
