The importance of spirit in raiding situations:
Disclaimer: I'm not a priest, but just trying to understand the gearing decisions behind it (yay loot drama)
At what level (if any) do you want to stop focusing on gearing spirit? I'm seeing conflicting reports on this -
the holy guide indicates that spirit is something that you gear for up to the point that you're comfortable with your regen.
The disc guide simply states that you should only consider items that have spirit. Are the two specs that different in their mana usage characteristics?
Similarly, what is the level of regen that healers are looking at getting to (for normals, and for heroics?)
Finally: is 4.0.6 going to change this much? (with Holy Concentration getting a mild nerf, and probably other ability tweaks?)
