I logged on the PTR and gave myself: Food Buff, Flask (Intellect), Blessing of Might, Mark of the Wild. I then used the tool-tips (did some healing to check for errors, should be correct) to find out what all of the new heals are doing. I then played with a few rotations to make sure they actually would work and put together theses charts. I did one set forged Mastery and one Haste. My item level is 545 and am 13/13 in 10 mans.
Few Notes: I am assuming no over-heal and 100% mastery shield usage. This is a raw output setup. So for comparison of output from other classes would be a mistake, but within our own rotational comparisons we can assume similar over heal and mastery usage from setup to setup.
For Sacred Shield usage I assumed you would do one SS after every HP finisher. This is about 7 sec so really you would alternate after every other. Could be better to use it on CD and interrupt your rotation but looking at the raw healing down per GCD I am not sure it is worth it to delay the HP finishers. Thus, I counted SS as half in the rotation since you would be doing it half the time in the rotation.
I have my full charts below and the comparison chart above. I was very skeptical about Selfless healer and Haste and now it looks like I need to take it more seriously. We are far from done with 5.4 tweaks but here is some cold hard math on heals and rotations. I will do my best to redo the numbers when we have significant changes. I will also “model” other rotations as people suggest them.
