Given proper timing, I can get a shield on the whole raid just before tantrum, negating about the first half of it. I can get a shield on the whole raid before Kologarn's "Oblivion" shockwave attack, almost completely nullifying it. For mimiron phase 2, i pretty much just chain-shielded, and it seemed quite useful.
If my shield absorbs 6k damage, and costs 600ish mana, I'm getting just short of 10 health per mana (if I don't get a rapture proc). When holy spec'd, my Circle of healing heals for about 2300 on 5 targets (or 11,500 total) for about 930 mana, this amounts to 12.3 health per mana, assuming none of it overheals. Shields only overheal if they're not consumed within 30 seconds, this is unlikely if you use them at appropriate times. CoH, however, can overheal by quite a lot, so it's efficiency is diminished by a bit. I'm not trying to say disc shield spam is better than CoH, just the the efficiency isn't terribly far behind, and it can really help by keeping the other healers from getting "behind" on healing when half your raid is sitting at half health.
My priest is only my alt, so I'm not up to speed on all the ins and outs of priest healing. But people don't die, I don't have mana issues, and bosses are going down.
Note: we always have a paladin for tank healing, so I've been trying this because I hate holy spec.
@OP: I think you'd get a better response if you'd get off this "disc priests aren't healers" trip. Shields are heals too, just backwards ones, and in many, many encounters, disc priests should be casting heals, not only shields. Penance is amazing HPS, especially with borrowed time up, and flash heal isn't too shabby either. Sometimes, direct healing is simply more useful. Maybe you should change your motto to "PW:S is a powerful raid heal." Comparing a disc priest to a healer is like comparing an affliction lock to a destro lock. They both serve the same purpose, they just go about it in a different manner, using mostly different spells.
