Despite going down over 2,500 mana out of combat and 1000 spell power, the 4 set was just insane. As long as you regularly spam holy shock when the cooldown comes up it is pretty amazing how much healing you can do with very little mana. I think my overall mana usage was even less than with my better ilvl gear. Got some attempts in on Feng and its insane but doable. So end of the story is in my experience, yes replace your gear with raid finder but make sure to look for upgrades it to regular if you can.
P.S. Highly recommend trying out holy prism now that it doesn't suck, especially on Feng.
