I am currently running the Spr > Int > Mastery > Haste = Crit Build with Holy Prism and Eternal Flame (Just to keep the IH buff up on peeps). 501 Ilvl.
I find that recount and skada both show Illuminated Healing doing around 40% of my heals, beacon around 20% and eternal flame / holy prism around 10-15% combined during 5man heroics.
I figured that illuminated healing is 'free', as it costs no mana to actually have that buff up, beacon is also 'free', and holy prism uses what 10k mana per min?
In 10mans, I find that IH drops to around 35%, beacon depending on fight raises to roughly 25%, eternal flame at roughly 15% and the rest is almost even with holy light, holy prism, divine light etc.
Wondering if any other holy pallies can show me some love and post up some percentages. I really want to get mana efficiency as best I can.
