I had a quick search but I couldn't find any details regarding the dispelling on Spine of Deathwing. What I wanted to know is whether or not Blood Corruption: Earth could still mutate back into Death upon being dispelled. The dungeon journal states that it does and the majority of guides I've read detail this, but I read that in a hotfix that they changed it so it would no longer mutate back. The reason I ask is because during our previous attempts on the boss I've been dispelling Earth cautiously to reduce the likelihood it'd mutate back into Death, but if it indeed did get changed then this'd give me a lot more freedom.
Any confirmation would be appreciated.
