As you likely know by now, Warlords of Draenor will be released on November 13, 2014. You’ll get access to those ten new levels, Garrisons, new thing, new that, a lot of Orcs, and so on. One thing you’re not going to get is a whole bunch of new abilities. In fact, you’re going to lose a few and a number of others will be changed.
You will get a few new talents, though. Also, in lieu of new abilities, you’ll gain various “Perks.”
In general, Priests received several significant changes, mainly focused on reining in Discipline’s damage absorption shields, improving quality of life for Discipline and Holy specializations, and solving single-target damage issues for Shadow. All of the new abilities will be tested and we’ll eventually get an idea if those “improvements” really did the trick. It should also result in cleaner action bars and smoother rotations.
As of this writing there is still another ten weeks to go, so expect a few changes to what’s below.
