Today I was running 10 man ICC on my resto druid healing with a holy priest and resto shaman. On Saurfang the shaman went ele and the priest and I 2 healed the fight. My question is if holy priests in general are having mana issues in current content frequently or if this is more an issue of the particular person's healing/playing style. We were both pretty similarly geared (~5000gs for w/e that's worth) but by the time the frenzy came the priest was nearly OOM. So next attempt I told him to save his mana CD's and I'd innervate him off the bat when he reached 50% mana. Then he used his mana CDs and was at about 50% again by the time frenzy hit, and shortly after my innervate was up so I used it again on him. By the end of the fight there was only one mark up so dps was pretty decent and even after the spam fest of 30-0% and mark healing I finished the fight at about 35% mana (used one alchemist's pot) and he was nearly dry (with TWO innervates plus his own CDs).
So are you holy priests noticing that there's a class based problem with mana regen/efficiency relative to other healers or is this most likely an issue of the individual player not healing efficiently or wisely. It still seems hard to see even if he wasn't the best healer how I could end the fight doing fine on mana (almost 40%) and he's nearly dry. I didn't have a single mana CD (just replenishment and pot) and he potted, used shadowfiend, the other priest thingie, and two innervates.
