Currently for Disc haste is huge in 10 mans. We don't bubble shield the raid anymore (which would be why we max mastery) but have to have that haste boost for prayer of healing, smite, and penance. If your not using those heals then no need for disc in 10s. Make sure you check which raid size you are studying stats for as well as if your tank healing or raid healing. Because for 25's mastery disc is tops with crit or haste not very important unless your job is tank heals. I am glad crit is making a comeback in 4.2
The one I was looking at was updated for 4.1 (elitest jerks I think). They basically said haste is better than mastery, or or vice versa depending on your healing style. I use all the spells you mentioned above, but I haven't done anything resembling a raid environment. Sifting the junk that can sometimes be EJ, Whims is right. Mastery will be better under seemingly very restrictive circumstances, while haste will help with, well pretty much every thing.
There are probably softcaps for both, I just have to find out what they are and gear/reforge accordingly.
edit: the mastery soft cap is based off your DA procs while saying you want 20% of the persons life as a shield using 0.3*1+(mastery/100) = DA% as the formula. So for tank healing you could really stack mastery for your DA procs (you will need less with 4.2 due to bigger crits). Even then I think you can make the arguments for haste being better. Meh I am more confused now than ever
