So after getting some feedback I've made several tweaks/changes to the level 80 talent trees which I've posted before here. Transformation was popular for many, but it was just as unpopular for many others. Replaced it with Fel Absorption which in addition to being nice on it's own accord has great synergy with Demonic Revenge. Reverted Pestilence to Blasphemy. Pestilence just didn't seem worth it, and while Blasphemy may be a little over the top it's tough to find something neither over/underpowered for Affliction.
Please do post in the thread or leave comments here on what you think!
