I think we're stuck with Chakra, Psychic Horror, lackluster CC (as Disc), and Inner Will being 2% movement speed for the forseesable future. Sadly, Blizzard has never been competent with Priests even at Expansion time, considered the last two or three tries have required major balancing hotfixes immediately (or not so immediate,) upon release.
LK,Cata, MoP were all ugly. Cata and MoP especially for Disc, LK for Shadow.
