I have seen a few questions out there asking about the viability of Holy Radiance as a single target heal. I think the question comes out of shock that anyone would use it as a single target heal over another heal such as Divine Light. I can see where the confusion, and horror, would come from as it is not powerful heal. As most people know we use HR primarily as a Holy Power generator. Its healing is really just a bonus. But we could “easily” do a beacon swap Divine Light with the no GCD glyph to generate HP as well. Is this play style viable? I think the consensus is no, in part to the lack of beacon transfer, but I wanted numbers.
There are 2 tables here. 1 figures in over healing numbers as follows:
- HR direct heal 25%
- HR Splash 10%
- Illuminated Healing 10%
- Beacon of Light 50%
- Divine Light 50%
- Daybreak 80% for direct heal
I find those to be average for most fights. But I also included a raw heals table as well. This is with a 570 ilvl 42% Mastery and 24% Crit.
What do we see? For a 1 to 1 match up of DL vs HR: Divine Light twice the heals as HR. When we hit 3 targets with HR it is even with Divine Light. At 6 Targets HR is clearly the best choice. This is true with or without over-healing figured in.
The issue is Day Break. Every time we pick a DL over a HR we give up a stack of Day Break. Day Break can have up to 90% over-healing when it does land it hits pretty hard due to the mastery shield and beacon transfer and the 25% higher crit chance of Holy Shock. So if Day Break hits anyone after using a single target HR instead of a Divine Light you end up ahead.
So is there a time where DL > HR? Yes. But it is rare. The time you would pick DL is for very spread out fights when HR will hit 1 target and then you holy shock a target with no one within 10 yards of that target. That decision will net you 56k more heals (~70% more). But if you DL when you could have hit 3 targets plus a Day Break proc, you lose out on 102k heals (~60% less heals). The 6 target HR nets you 238k more heals!
