Except we are not talking about the first line of a book, we are talking about the entire first chapter. And that chapter was hastily put together with no care for any details.
Oh, so all that matters is that they use the void? The story of those elves, their numbers, their names, their outlook on things, how the transformation changed their view on things, nothing that makes them a people matters?
Lightforged draenei have little lore, but it's still a ton more than the void elves. Just by looking at their support cast we can see them way more varied than void elves. Lightforged draenei have characters like T'Paartos, Y'mera, Enaara or Telaamon to diversify them, as well as supporting cast like Quoram or Lothraxion. Void elves have Umbric, and that's it.
Heck, the LF recruitment story with T'Paartos has way more about what means to be a Lightforged than the entire void elf storyline so far can show us about the void elves. The only elf with void powers that was deeply explored was Alleria, and her story has nothing in common with Umbric and the dozen nameless elves that followed him and lived in a floating rock in the literal mid of nowhere.
I can't dislike what doesn't exist. I can dislike the absence of it, thought.VE might not have a lot of lore, but they do have it. And dismissing it because you don't like it, is dishonest.
