Finally, someone else explains it. The only Void-based healing spell that priests have, not counting the glyphed version of Penance, hurts the target, yet the void elf paladin crowd always insists that it would make sense for a Void paladin to be capable of healing the same as a regular paladin with no drawbacks whatsoever.
THIS. It’s a concept cooked up by the likes of Reddit and MMO-Champion, yet so many people have latched onto the belief that it’s something that Blizzard would ever actually do. Making an exact copy of an existing class but with different visuals would be lethargic even for them; at least allied races were given unique racials.
