Shadow Priests have been up in arms all over the official forums recently, and it seems to have reached a bit of a breaking point. Rather than waiting for the official Priest Q&A in the developers' Q&A series, Ghostcrawler chimed into an unofficial Q&A thread to give some insight. Since it's unofficial, the questions asked are very direct and specific, aimed at the posters in that thread rather than the playerbase as a whole. Still, the tone is mostly the same: Don't expect major announcements while reading the thread, it's more a discussion on class direction and philosophy rather than patch news. That being said, there is some good news in the whole thing. Some bad news, too.
I strongly recommend reading the whole thing on the official forums, but I'm going to pull out some bits and pieces here.
The first big thing that jumped out to me was in response to a question regarding Haste and DoTs. Have they considered DoTs scaling with Haste? Ghostcrawler says... yes! It's something they're apparently actively discussing. That doesn't guarantee we'll see it, but the fact that they're talking about it is promising.
