Void Elf Paladins are recruited Telogrus Rift High Elf Wayfarers
“There’s just one question: If they come from a small group of Silvermoon Exiles, how are they an Allied Race? Where do the numbers come from?”
“They start out as a small group,” Danuser continues. “But it’s natural as other elves have found out about them — elves who are interested in new sources of magic, power, or opportunities — would see if they could undergo a similar process.”
-Steve Danuser, Lead Narrative Designer for World of Warcraft

Void Elf Paladin Anti’s like to ignore that canonically, playable Void Elves come from two different populations.
The first being the Void Infused Blood Elves seen during the Allied Race Questline, and the second being High Elf Wayfarers who are not Void Infused but rather are dabbling in the Void, hence the introduction of High Elf skin tones, eye colors, hair colors, and the option to remove tentacles from our hair.
This goes hand in hand with Blizzard making Sandfury Trolls & Wildhammer Dwarves playable through the addition of customization options.

It is clear to everyone that the Void Infused Blood Elf population of Void Elves would not be able to be paladins, however the High Elf Wayfarers lore-wise would be able to.
A Void Elf Paladin hailing from the High Elf Wayfarer population would be the equivalent of a Discipline Priest. Light & Void are forces that can be utilized by the same individual as long as it is done with care, as seen by Anduin Wrynn, usage of the Netherlight Crucible, and the Priest order of The Conclave made up of masters of the Light & embracers of the Void,
“For light cannot exist without darkness, and darkness without light.”

But how do we represent this ingame?
A simple gameplay solution would be to lock Void Elves from utilizing Void customizations when the Paladin class is selected. This includes disabling the usage of Void skin tones, eye colors, faces, and hair tentacles.
A similar concept is already used in game for Death Knights, where certain customizations are only selectable when choosing the Death Knight class. Additionally, selecting regular skin tones when creating a Void Elf already locks you out of selecting nearly half of the Void Elf face options in the live game.
We have the technology, and we have the lore.
Lets make it happen Blizzard
