Again, I'd like to stress that I'm not advocating a rose-colored, idealized (and idolized) picturing of the elves in SR (or in any other game). Yes, they're snobbish, yes they frequently have a superiority complex, yes they tend to be insular, bordering, or frequently going straigth into racism-land.
I know that, that the writeups shows those isn't a problem, for me, in fact I like that.
However, the corebook said only those things and the positives were only their physical characteristics in the writeup, but even those were in a contxt of the above. Like it was written by a bitter member of the other metatypes. That's okay, I'm okay with in-character stuff like that. I just think a core "race" writeup in the game's corebook should be a bit more fair. I think I liked the 3e version the most, where every metatype writeup was written by a member of that type, in character.
Run faster was a bit better, it talked about more things, but ultimately that was the same feeling I got: the author ultmiately has nothing positive to say about elves, to balance out the negatives. Even the things that could be positive were casted in a light that made them shallow-looking and again, the most "positive " thing was that they're pretty. Agin, it talked lengthily about how insular they are and how easy they got life in general, because they are pretty. Conversely, the3e writeup said, that they are elves not comforting to the ideal picture and they are quite miserable for it (granted, Run Faster talked about that too, but only in one or two throwawy sentences). 3e also talked about that elves are living in the barrens too, that not all of them got it easy. The miriads of demeaning little prejudices they're facing up every day. It flat-out said that yeah, we got it better than the other metatypes, but that doesn't mean that everyone's live if just rose and sunshine in elfland. Other things could have been highlighted as positives, like their general greater regard for nature.
That is the nuance I missed a bit from the 5e books. It's not that the writeups are bad, as writing, it's just I felt the writer here makes a statement about they negative view on the metatype, instead of writing a non-flattering, non-idealized, but neutral writeup about it. Combined with the relative sparsity of "cool" pictures with frontline elven characters in the books and I just got the feeling that it was at least a non-consicous choice, that in this edition, elves will get the shaft and I don't think that is a good thing, because rulebooks should portray those things without such bias, IMO. In-character material in the books in the books could be very much biased, yes and I'm aware that the Run&Gun material was written as such, but still, if it is an ICC thing and biased there should, ideally, be material to balance it out.
Make no mistake, I'd say the same about any other metatype, if this thing would have came up with them instead, or conversely, if the elf writeup would have been overly sugar-y.
