Well I don’t recognize you so I’ll assume you’re being genuine, but the distinction isn’t so much about race as much about faction.
Honestly the distinction is pretty simple to grasp.
You’re from the USA. I’m from Lebanon. We’re both humans but we have vastly different experiences, even though we share most of the same experiences. In terms of our time on Earth, we can’t be more alike while also being different.
Doesn’t matter what you call em. High Elves. Blue Elves. Storm Elves. They’re all elves, specifically Highborne Elves…specifically “high elves”.
And it’s basically been 15+ years (even more if you count Alleria’s squad) of divisions between the high elves that are on Alliance and the high elves that are on the Horde. Lots of story and context and fun to be had. Unique characters. Interesting interactions. Ups and downs. A fun “civil war” of sorts that plays second fiddle to the whole Human/Undead (which carry almost the exact same themes except one has death and one has the whole fel business).
People, like myself, want to represent those experiences through playing those Alliance High Elves. Sure they, at the moment, are basically just blue eyed blood elves. But character creators are arbitrary. They don’t have to be the same.
So yea… honestly the name is irrelevant… call em what you want. What they are is obvious though, unless you’re trolling. You probably aren’t.
All there is to it, and I’ve repeated these things enough that I could have a Master’s degree in High Elf history so I’m no gonna go in loops debating it.
