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
Prece de Cura is the AE equivalent of Gheal and
Palavra Sagrada: Santificar is the AE equivalent of
Cura Célere. (Yes, I know Disc doesn't have
Palavra Sagrada: Santificar - 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
Palavra de Poder: Escudo and a 150% mana return on a
Palavra de Poder: Escudo. When we tried PW:S at 50%, it became too efficient to use nothing but
Palavra de Poder: Escudo. We aren't trying to kill
Prece de Cura use completely, just shift to a balance where
Palavra de Poder: Escudo and SS are used for absorbs, and
Prece de Cura is used for healing. Yes, Disc
Prece de Cura will be weaker than Holy
Prece de 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."
