I want to suggest massive glyph that would actually change very little effort-wise. Just create two glyphs! First glyph (Light Mastery) will change color of shadow abilities from black-purple into yellow-white. Second glyph (Shadow Mastery) will make similar effect like first by changing light into shadow.
Profit?
Lightforged Draenei can be Spriest and Discipline without breaking immersion (And even Holy unfortunately have shadow abilities)
Void Elf can be Holy and Discipline without breaking immersion. ( And even Spriest unfortunately have light abilities)
Undead will benefit
Lightforged Undead will benefit when it happens
IMO Priest as a class require huge rework or even separation between Holy and Shadow… but this glyphs or quest chain (similar to green fire) would fix a lot of problems!
So basically same as the idea for Class “skins”? I do agree though.
I hope they introduce this to other classes’ specs/races, because some of them don’t really make sense. Like in the case of the priest races as you said.
This is true with priest since it has two fundamentally opposite specs. Is like if DK and PLD were the same class. Shadows shield is still a light shield with sparkles… and it makes no sense.
Shadow mend is ok… if a bad sound and animation…
