So, when U14 launched, I immediately went over to Faerun and started questing, and rapidly discovered that my spell pen is nowhere near up to the task of dealing with drow, so I pretty much stopped using Destruction entirely.
Today I went back to Stormreach and ran some old epics, when I remembered that what I was fighting didn't HAVE any SR, so out comes Destruction again.
The third monster I faced made it's save...and died anyway. 464 points of damage.
I did not see anything in the release notes about this. The old 50 points it used to do was kind of a funny joke, but suddenly this is an incredible viable attack even when it doesn't officially work. Monsters in e-N Devil Assault were being taken to half health (or less) on a successful save, and dying on a failed save.
