Also, but this has been up for debate in my guild, but I think Divine Light is not worth casting right now. It scales too poorly compared to FoL. Flash hits just a bit softer, for a tiny bit more of a mana cost, however casts for 40% less time. Add in the FoL glyph, and that's what I'm switching too.
This actually sounds quite attractive! Considering most of us aren't stacking haste like we traditionally would at the start of an expansion, DL is extremely slow. I'll probably give this a shot tonight and see how it feels.
So what is the verdict like?
I've seen mogushan LFR. Holy pallies are horrible on heal meters. Sucking in AOE like we have always been.
As others mentioned, LFR is a terrible place to analyze things. However, I don't think our AoE is as terrible as you make it sound. Holy Radiance + Holy Shock for daybreak healing certainly isn't anything to write home about, but it does a respectable amount of clumped raid healing.
Also prism or hammer?
Hammer, hands down, for 25 mans.
How are 10 mans?
WoG/EF > LoD
Prism > Light's Hammer (I would assume this is the case anyway)
Also, what is the most mana optimum rotation? Right now, the only way to generate hopo is shock and radiance. I don't see myself using HR all the time. So what do in a 10/25 raid setting?
Or are we doomed to always heal the tank?
Not sure I know the "most mana optimum rotation" but I can certainly tell you that it involves very controlled use of Holy Radiance. I try my best to always cast Holy Shock after a holy radiance as it's just free additional healing through daybreak. You can also generate HoPo in a pinch with CS or ToR.
Overall, we're definitely moving slightly back into a "tank healing with raid support" role, which was basically where we were in T12 and probably even late T11. I can't say I mind the role at all. Yes, it will take some getting used to again, but I like our toolkit and I like that we're competitive in nearly every aspect of healing.
