So thats a nerf to elune, related to the types of the winter queen, but i guess it should have been expected since they have been nerfing her a while being unable to intervene for her priestesses death and fate in the maw but also that leatherworking quest in bfa saying tyrande controls the majority of elunes power, i imagine that constalletion isnt even an actual one but just visually visible only in ardenwealde, or she is being weakened by something but that would mean shes much stronger than her sister or was anyways.
