In Dalaran’s case, it wouldn’t really affect the current characters, as its recent history has diluted whatever uniqueness it’s culture or people may have had.
After being the neutral base for a wide range of factions, being used as the main hub for several notable campaigns that hosted armies from all races, and the further disolution of most of the aspects that made it a proper human kingdom, I’d say that its “native” population would’ve already dissolved across all other human settlements.
That said, giving it a history like the one i proposed would give more depth to its background and for example, explain how the few architecture that remains, has such a unique aesthetic when compared to that of other human settlements. Just to name an example.
We have Orcs, trolls, and Dwarves.
And in certain sense, we also have that for Night elves in the form of Blood, High and Void Elves.
Only in their case, their evolution was far more drastic. Even if it wasn’t enough to actually consider them a different “race” (as they are still call elves after all).
Its relatively hard. And its doubly tough, if we are predisposed to think ill about any attempt at it (which to be honest, at this point we’d have every reason to).
But the truth is that at some point, we must address the elephant in the room in some way.
Even if its fantasy, the internal consistency of the setting cannot simply hand-wave obvious and dominant physical differentiation amongst the people from the same race.
Yes, from a meta perspective diversity is really important.
No fantasy should feel as if it excludes any collective.
And yes, it’s important that when dealing with those races that resonate more with RL, it should be done with care and sensibility.
But yeah…I think that just as it happens with any other race, its an aspect that to a lesser or greater extent, must be addressed at some point.
It can’t be this obvious that we are to have like twelve distinct troll tribes depending on how they look, but for humans its just…" Well, we just want diversity, so let it be".
And I’ll repeat, this is NOT about looking for a justification to include any racial phenotype. But we can’t just dismiss the obvious relevant aspects these features imply from a worldbuilding point.
I’m sorry but if we are to start taking the games story in any seriousness, we just can’t turn a blind eye to this sort of things (*)
Humans in WoW, are but another Fantasy race whose heritage and ancestry goes back to a similar background as Orcs. And just like the latters diversity leaned on a more or less internally consistent development, I’d expect a similar one regarding humans.
(*) About this bit, there is of course the alternative of rather keeping it shallow, and letting people fill the blanks with whatever head-canon or self-insert they find enjoyable. Totally understandable, and not at all negative. Not condemning either posture.
But if we are to set the bar there, then maybe we should also stop hoping for the better or more developed stories in other lore aspects. Either you take the story “seriously” as a whole or you don’t.
I’ll repeat, have a blank sheet of the lore, with memes, references and all can indeed be very very fun. But then again, do not expect much more development in places where shallow pop-culture references have already filled the void.
