With the revelation of the new cosmic map of WoW that retcons Chronicle, coupled with the thematic class changes since Legion, WoW needs to clarify what type of power each class uses and where it comes from because it is currently inconsistent.
Death Knights, for example, do Shadow damage, and this makes sense because we have learned their power comes from the Shadowlands and the Jailer whom specializes in Shadow/Domination magic.
Warlocks also do Shadow damage, which is inconsistent because their damage comes from Disorder and Fel, as it stands. Warlock Shadow damage then, should not be called Shadow damage. It should be called Fel or something synonymous.
Shadow Priests are the biggest outlier, because Shadow is in the name and in the damage, but in Legion Shadow Priests were turned into Void Priests. Their power is now canonically Void power, but they’re still called Shadow Priests and do Shadow damage, which is inconsistent. Blizzard renamed the “Void” section of the cosmic map to “Shadow,” which is also inconsistent, because you have the Shadowlands and that Shadow magic, which is hitherto not the same as Void magic- its Death. Shadow Priests then need to either be renamed Void Priests, as their entire class fantasy is now based around, or Death Knights need to just do “Death Damage,” or something synonymous.
Mages vs Druids you have Mages doing Arcane magic from the “Order” portion of the cosmos, and druids doing Arcane magic via Elune Power. So, again, which is it? Clarify where these damages come from, the sources of power.
In the example of the first 3 classes you have them all doing Shadow Damage, and yet their damage comes from completely different parts of the cosmic map. So what is it? If this is how its supposed to be, then explain how it is not inconsistent. If you can admit its inconsistent, then make the necessary changes. Fel magic, Death magic, Void magic, etc.
Finally, this isn’t a speculation or debate post. It’s a matter-of-fact this is how the game is versus this is what your map says post, and I’m asking for the inconsistencies to be plainly clarified in game. If you’re going to call your new map the “Refined Cosmology,” then refine the details. Enough of these broad-stroke claims without addressing the manifold detailed implications in-game.
