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
치유의 기원 is the AE equivalent of Gheal and
빛의 권능: 신성화 is the AE equivalent of
순간 치유. (Yes, I know Disc doesn't have
빛의 권능: 신성화 - 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
신의 권능: 보호막 and a 150% mana return on a
신의 권능: 보호막. When we tried PW:S at 50%, it became too efficient to use nothing but
신의 권능: 보호막. We aren't trying to kill
치유의 기원 use completely, just shift to a balance where
신의 권능: 보호막 and SS are used for absorbs, and
치유의 기원 is used for healing. Yes, Disc
치유의 기원 will be weaker than Holy
치유의 기원, 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."
