Blizzard have given Priests a heads up that there will be updates coming soon for all three specs of the class, as they gather more feedback.

Hey priests!

I just wanted to take a moment and cast Power Word: Update to let all of you know that we’re gathering your feedback and deliberately taking some time to make sure our next steps are hitting the right notes with priest and that they address a lot of the feedback provided by the community. Please keep it coming and we’ll be back here with updates soon for Holy, Discipline, and Shadow.

Your feedback is incredibly helpful, and we appreciate you taking the time to share your thoughts. Thank you for your patience!
