I'll be really frank here. I don't think the group portion of the heal is long for this world. I personally dig it and I feel smart when I see 5 people in a group all at once who need healing. It makes the spell different from other AEs.
On the other hand, it's pretty gamey. (I can only heal these five arbitrary people, why?) Priests feel like they have to ask raid leaders to set up groups with their weird AE spell in mind, which is really unlikely to happen in Raid Finder. It doesn't work at all on encounters like the shrines in Sha of Fear.
We're not going to change it for 5.2. We're probably not going to change it for 5.3. But I sense the writing on the wall here that it won't last much longer. I can imagine a future iteration where
Preghiera di Cura is the AE equivalent of Gheal and
Parola Sacra: Santificazione is the AE equivalent of
Cura Rapida. (Yes, I know Disc doesn't have
Parola Sacra: Santificazione - I'm in a really theoretical space here.)
Sorry. I broke my own rule about simple questions and answers. Sometimes I can't help it.
At the moment (which could still change) Rapture provides a 25% cheaper
Parola del Potere: Scudo and a 150% mana return on a
Parola del Potere: Scudo. When we tried PW:S at 50%, it became too efficient to use nothing but
Parola del Potere: Scudo. We aren't trying to kill
Preghiera di Cura use completely, just shift to a balance where
Parola del Potere: Scudo and SS are used for absorbs, and
Preghiera di Cura is used for healing. Yes, Disc
Preghiera di Cura will be weaker than Holy
Preghiera di Cura, but that is offset by the incredible benefit brought by absorbs. Please don't interpret this as "Because absorbs are so good and because absorbs are my thing, it is a design failure if I ever cast an actual heal."
