Again, in lore, Forsaken priests are shadow priests. At least the bulk of them are. There are a few Forsaken priests that tap into the light. Alonsus Faol is one such Forsaken. But the bulk serve the shadow.
That doesn’t impact our characters though. Blizzard wouldn’t ever put players in the position of not being able to play a class properly because of the lore. If they did, the only spec Forsaken priests would have access to would be shadow, which would be boring and would mean folks would need 2 priests if they wanted to heal and DPS.
Old post but I’m against UD pally because that kind of conflicts with the Priest theme. God knows that paladins already overshadow them enough, being people that can abuse and mix both powers that are naturally seen as “good” like the light and powers that are darker like the void is like the only difference they got from just being worse paladins storywise at this point.
Problem is Warcraft is a stupid kids knock-off version of Warhammer which is itself a knockoff of D n D.
There is no high fantasy reason, ever, that undead should be able to use Holy magic. Also, Blizzard aren’t the sharpest knives in the drawer. That Q & A doesn’t really change that the answer is incredibly stupid and illogical.
Per that answer, it being a matter of willpower, Alonsus Faol is obviously an exception because he was also, idk, THE POPE of Azeroth who headed the Northshire Abbey/Clerics of Northshire and the Church of the Holy Light and created the Paladin order in the first place.
This part right here kind of explains it away though. Yes possible, but really not the best idea. WoW has so few RPG elements left to it. If we can at least keep the race archetypes in tact, I would personally prefer that.
