Yeah, and the old "can't do it because of lore" reason has never been more invalid than now that quite literally every single paladin is the Highlord of the Silverhand, wielding the Ashbringer itself. At least the people who hunt down the legendaries have to earn them.
By percentage of their respective populations, there are still way fewer demon hunters wielding the Warglaives of Azzinoth than there are paladins swinging around the Ashbringer. And that's even considering that the warglaives are more popular than the Ashbringer and that demon hunters only have two specs.
