I would much prefer there to be an explanation as well, so long as it’s told through the world and not through some filler NPC-bark or throwaway cutscene. The reason as to why they might want to avoid creating an explanation at all is because… well, it gets awfully political, doesn’t it?
Which is a bit ironic when it comes to WoW, to be honest. People call you racist for simply asking a question, meanwhile the game we’re discussing portray East Asian stereotypes with a race consisting of Kung Fu Panda bears.
Most of the original races in the game borrow from real life cultures as well. Trolls are Jamaican, Orcs supposedly portray black culture and Tauren are inspired by the Native Americans. The European feudal aesthetic however, is of course portrayed by humans! People have written scientific papers examining the textual narrative of World of Warcraft and it has kinda always been inclusive yet racist all along. Some might view this as something that is problematic, but I personally don’t. People like and respect these fantasy races, and Blizzard has treated their source inspiration with respect, not disdain.
However there is still potential in the world for them to expound upon. Like the Wastewanderers in Tanaris. They’re obviously influenced by the real life Bedouins, and the real life Bedouins are awesome. It would be super cool to see the humans living in that area of Azeroth get some more love, but let’s be real… we’re heading to the Shadowlands™ …
Played the intro once but didn’t think much of it. Never really finished the core story for the alliance, either.
