Lord of the depths
That is the thing. If you object, you are questioned about why it’s so important.I don't recall saying a +2 Con is the only thing a dwarf is to me.
I don't even remember saying a +2 Con is the only thing a dwarf is to me mechanically, which I almost consider a fair- if mistaken- interpretation of my words.
But to answer the question you asked, because having that +2 Con is important enough to and for the character in question that it trumps any and all other criteria for choosing a race.
meanwhile a whole book is there saying that you can change it around because it does not fit someone’s vision and by extension is important.
the +2 is meaningful for a character or it’s not. We could also ask the elf who places the +2 in charisma if that is the only way he defines his character which is also uncharitable.
