Reading the recent blue post, I saw that Blizzard expect us to be able to heal just fine in heroics with 1800 spirit. Sounds good to me, I healed fine in ilvl 329 gear, but it made me think about how much spirit I have and if I need that much. I plan to get into raiding soon since I have an average ilvl of 345 (stupid healing trinks won't drop) and I have quite a lot of spirit, WAY too much for heroics (never have to pop cooldowns anymore and usually stable above 50% mana left). When does it start to become a good idea to reforge spirit into haste/mastery? How much spirit, non raid-buffed, should a holy priest aim for? (More is better, sure, but having tons of mana left after a boss is a waste of other stats).
