The coefficients of these spells were hotfixed last Thursday I believe.
Corruption's coefficient went from 0.156 to 0.20.
Immolate's coefficient went from 0.13 to 0.20.
This ends up being a reasonably significant dps buff to all 3 specs. In our preliminary testing, Demonology may have benefited the most.
Please recognize the changes these numbers will have on your class when making subsequent posts.
Can you link that blue post?
It's in the patch notes now.
