Allright, I’m seeing a lot of confusin going around and feel like this needs to be explained.
Lets start with high elves (species):
By this we mean what is genetically a highelf, they are the decendents of the night elf Highborn who were banished and moved to the Eastern Kingdom to find a home. This species found a place in Eversong Forest after kicking out the dirty forest trolls. That came to an end however when Arthas showed up and ruined them.
After Athas’s invasion, the Highelves (species) were seperated into several different groups. Some took up the name of Blood Elves (faction), some seen the Blood Elves (faction) as just out for mindless vengance and refused to take up the name, sticking to being called The High elves (faction).
Within the Blood elves (faction) there was another seperation, some who followed Kaelthas (Bloodelves (faction-Kael)) and some who stayed in the city (Bloodelves (faction-silvermoon)).
The ones who refused to take up the name, The High elves (faction) stayed loyal to the alliance, and have been part of it for the past 25 years of gaming history. This is the Highelves that people are requesting. A reasonable request at that.
The Bloodelves (faction-Kael) went off into outland and joined the Burning legion, they are hostile to both Horde and alliance.
The Bloodelves (faction- Silvermoon) Are the ones who joined the horde (which was bad writing and makes no sense, but, different topic and 12 years too late now) There was another splinter group of these guys who were exiled and became the Void Elves (faction)
The Void Elves (Faction) ended up reconcecting with the High Elves (Faction) And joined the Alliance.
I hope that clears things up for people who say ‘bloodelves are the high elves’. Because you’re wrong, Bloodelves are a single group of the species ‘high elf’ but are infact not the faction that is requested, knowen as The High elves.
TLDR:
High Elf (Species) = Genetic Species that all Sin’dorei, Quel’dorei and Ren’dorei belong to.
High Elves (faction) = The High elves of the Alliance, who are highly requested.
Blood Elves (Faction - Kael) = The group of Highelves who renamed to Bloodelves and went off to join the burning legion.
Blood Elves (Faction - Silvermoon) = The group of Highelves who renamed to Bloodelves and eventually joined the horde.
Void Elves (Faction) = The group of Highelves, who renaed to the blood elves, then got exiles and became the void elves and then rejoined the Alliance, again.
