No, because the point in increasing the outdoor world buff was to go along with the scaling done so that the leveling process feels proper instead of one shot this and that. The raids are not a part of the leveling process for almost anyone.
The old raids were mostly a go back and take a look at old stuff and farm some mogs, mounts, gold in your spare time. They kind of kicked that in the teeth, and I'm guessing it is an accident since they never mentioned increasing any scaling for the old raids or health changes. Appears to be an unintended side effect of the change, until a blue comes out and says otherwise.
This isn't to say some aren't going to like this change, but overall most folks are going to be against it. I'm leaving out those who don't care. Especially without Blizzard mentioning this as an intended thing. It feels like an accident. Didn't we have this happen before and the same outcry?
