Unfortunately, this is where disagreement sets in.
No matter how one views it, the fact remains we’ve been given settlements, even reputation factions for a race that used those very same assets. High Elves. The Silver Covenant. These were blatant Alliance groups, and from the moment Blood Elves were added in Burning Crusade, virtually all of their assets were used on this Alliance race, on these Alliance organizations and factions.
That the Blood Elves were playable and High Elves weren’t isn’t being argued, but while High Elves were present in Stormwind and other Alliance settlements, I don’t think one can argue that the customizations, the race, purely belonged to the Horde by any meaningful metric. It was a race divided by the factions, and that made them interesting, both sides.
The fault here lies in Blizzard for not distinguishing High Elves from Blood Elves by any meaningful visual means other than blue eyes. Allied Races would’ve been the chance to do so. Make a High Elf allied race, update their NPCs. Different hairstyles, maybe a different stance the way Nightborne had a different stance, but no. We didn’t get that. I can’t imagine we will in WoW’s lifetime.
The opportunity has been lost. Its time for Blood Elves to get some new things, but its no longer possible to create any sort of justification to add a Blood Elven customization and deny it to the Void Elves, not when Void Elves came from Blood Elves, and Blood Elf players have spent years constantly stating they are High Elves.
Dark Rangers/San’layn, Felblood Elves, Light-based customizations, are all things Blood Elves would have that Void/High Elves wouldn’t, and I think adding those things which are asked for will do more for Blood Elves in the long run than trying to ask for more Blood/High Elf customization and then claim it only for Blood Elves, or vice versa. Farstrider/Ranger tattoos/warpaint and scars are not something that is unique to High/Void Elves, and any such customizations made for them should be applicable to Blood Elves.
