It is actually funny that you would mention this. Before Mists of Pandaria, I was always a fierce advocate of Haste for Discipline Priests. I like Haste for more than just the throughput, but also for the precision and control that it offers you.
With Mists of Pandaria, I went against my "gut feeling" of recommending Haste again, and decided to recommend Mastery based on the things I noticed on the Beta so far. The main reason, I would say, is not Spirit Shell, but the fact that casting Power Word: Shield is much easier to do. Mastery benefits you directly there. It also means you get more Borrowed Time uptime, meaning that fewer casts overall need to be affected by Haste. This is of course for a general/single target priority.
For heavy AoE, I believe it is quite possibly a toss-up currently between Haste and Mastery. Perhaps it can be boiled down to the same discussion we had in Cataclysm (Mastery = absorb more; Haste = get the AoE heals off faster, which means you could get the second heal in before the next tick of AoE damage).
Stat priorities for healers are always problematic, as I'm sure you know. This is the case even more so now that we are in a transition between level 85 and 90 scaling. I'm definitely keeping a close eye on these stats, and I'm personally rooting for Haste.
We are pretty much on the same page then.
Throughout Cata I have favored haste since while Mastery did/does affect shield (and other absorbs though not as highly imho), I find that my raid's biggest "sticking point" so to speak has always been raid damage rather than tank damage and I feel haste gives more bang for the buck with that.
That may change at 90, obviously, but for the moment with the new skills, I am still finding that haste gives me more. Going all mastery gives me only about 4k to my shield and about 500 absorb per PoH DA. For me, the slight increases to shield strength aren't worth the greater cast times.
Thanks for the reply, I am rooting for Haste as well.
