It was easily hitting for too much in PvE too. One of the most obvious hotfixes.
I doubt we will be in a bad place even after this change dpswise, though it does again leave us with some odd talent picking. I'll try to see how it's affected my own dps in a live environment if we get the Icecrown raid rolling tonight/weekend.
If the dps now warrants a buff, I would very much like to see SS added to Unholy Blight as well. It would make those talents feel more cool at the same time.
