I can understand the mechanical reason to remove it and will even enjoy it on my two Voidweaver disc but please let me keep it as an option visually for my Holy-themed one. It’d also be great thematically for the Actual Holy spec too, the graphic/animation already exists so it’s like just assign an item code slap it in priest class hall vendor!
The mechanical reason is a bit of an curiosity anyways, especially for Void Weaver. Inconsistency with Twilight Equilibrium is caused by Disc having too many Shadow spells in their rotation- between MB, Smite becoming Void Blast, and Shadow Covenant turning Penance, Divine Star, Halo into shadow, a holy damage spell was not consistently up to press. And now they take away Purge the Wicked.
I guess it allows Encroaching Shadows/Revel in Darkness and Abyssal Reverie to be taken together.
