It does, because it is an inconsistency. That both races were given the same customization, and why only one race utilizes them canonically is a question worth asking. Why a Wildhammer would dress a certain way, is not. We already know that Wildhammer dwarves are an active military force within the Alliance, why one might join the league is not any inconsistency.
The community certainly has not, and the proof is in any post made by a Void elf claiming to be a High elf is littered with responses reminding them they are a Void elf, and that their helf customization is an RP tool. It’s why the helf community is so excited about spotting Void elf NPCs using high elf customizations as well.
It begs the question, why hasn’t there been? Why has blizzard taken so many opportunities to show us blue eyed blood elf npcs, but we can’t see a single Void elf npc utilizing them? It’s not like Blizzard hasn’t given Void elves attention, or lacked opportunities to showcase this diversity among them. The moment we can clearly see a Void elf with high elf customizations is the day a lot of people will put their foot in their mouth.
And Blizzard is aware of this, so why are they so reluctant to add Void NPCs that use high elf customization? Nothing has stopped them from adding Blood elves using high elf customizations. You can’t say it doesn’t matter, because it clearly does, or else we wouldn’t be having this conversation.
