Probably me - while i love the forest elf society, I’m keen on the dark elf and actual kaldorei soceity coming to life - a lot of how the Night elves actually live culturally is not known.
Much of the defining features of the people would have been set in the pre-sundering era - with the Long vigil a period of martial alert - Darnassus, and now Suramar give stronger insights - but Darnassus didn’t show much of Night elf life in game - and it is interesting because the Darnassian Long Vigil is over and 10k year isolation with pure forest living, high martial alert and arcane abstinence is over - they now move back to doing civilization like it was before the great sundering upheaved every aspect of their lives. Here one would hope to see a lot of things missing from the Long Vigil, but present in the pre-sundering era return, giving a lot of flavour and an interesting cultural dimension that is part of an ongoing evolution of the stories of the races.
And Suramar is focused on invasion period of the pre-sundering era, which like the Long Vigil, wasn’t the normal period for the race. We do see a lot more detail of night elven pre-sundering invasion period life, but again it’s snapshotted to a high stress period, so whiles a bit more is available to be seen, there is still a lot not known in a normal setting - call it fanatical curiosity.
Saying that, I do want to see more of the Highborne society and for it to have a larger role when we get to visit the Night elves. I think it keeps the race interesting and varied, and its presence and relevance helps make the race true to it’s original purpose which is this arcane/nature, dark elf/wood elf duality which I really like about them.
VIsit my post here on why I like the Night elves so much.
