Nightborne and Void Elves should be able to be Demon Hunters

To be fair so can Blood elves, but it’s explained that they “bend” the Light to their will rather than the “Traditional” method of using the Light, I don’t think Paladins/Priests are necessarily “suffused” with the Light, it’s more like they have a deep connection to it naturally that allows them to easily channel it externally, we usually see Light-forging/infusion as being a step beyond the typical “priesthood”/Paladin position.
