As a thought exercise I took the stats from 3 random holy paladins at various item levels: 520, 550, and 570. I put in their stats, raid buffed them, then ran my throughput numbers for an EF build doing a strict HR-HR-HS-EF rotation while using Holy Prism on CD. Typical over-healing numbers were used like 50% for beacon and 10% for illuminated healing. I then took their spirit levels 13k, 15k, and 17k and found out how long they could go before they went OOM with 25%, 35%, and 45% haste levels. My results are below:
The two major things I drew from these charts were:
- How much of a total output gain going up an Eternal Flame break-point is worth over a minute of healing.
- How extra seconds of before OOM turn into healing.
You can clearly see the output gained by not going OOM. You can less so clearly see the extra output of Haste (the lower haste builds used all of the extra stats as mastery) over higher mastery builds. You can also see the huge difference gear makes in output in that 570 ilvl does about 75% more healing than 520 ilvl!
My last important point is that if you don’t OOM in a fight, because you should never heal as a strict HR-HR-HS-EF rotation, then you gain no healing with higher spirit/less haste. So it comes down to throughput when you need it (mostly). But going 25% haste to 45% is worth 5% more healing on average. But if you OOM you risk to lose 10% healing. Less risk than mortgage backed securities!
