Priest healing power and efficiency chart

Don't even get me started with Nature's Swiftness.  Instant-cast 2500 hp heals are just wrong.  Damn Druids.  :)

*innocent look*

*purrrr*

And don't forget about our restoration talent that reduces a 3.5 second healing touch to 3.0 seconds!

Here's a small table I worked up to compare the effects of +heal on the lower ranks of Healing Touch:

Code:

Rank 6 healing touch
 +0 healing: 2.11 HPM, avg heal 633
+50 healing: 2.28 HPM, avg heal 683
+100 healing: 2.44 HPM, avg heal 733
+200 healing: 2.78 HPM, avg heal 833
+300 healing: 3.11 HPM, avg heal 933

Rank 10 healing touch
 +0 healing: 2.61 HPM, avg heal 2060
+50 healing: 2.67 HPM, avg heal 2110
+100 healing: 2.73 HPM, avg heal 2160
+200 healing: 2.86 HPM, avg heal 2260
+300 healing: 2.99 HPM, avg heal 2360

As you can see, this mirrors the conclusions above, if you can manage 300 or more +healing, rank 6 healing touch actually becomes more efficient than rank 10 healing touch. There is a tradeoff of course, if you have to cast rank 6 healing touch more often, then you aren't getting back as much mana regeneration.
