To be honest, I have not had the opportunity to raid on the PTR yet so this post is more of a place to discuss the question. Looking at the math though, it would seem that +16 intellect et al. is still the way to go since Illumination is getting cut once again. However, with the changes to Beacon of Light and the FoL+SS mechanisms, does +19 spellpower become more attractive?
Would love to hear what my fellow pallies think.
