So i was looking on EJ and trying to figure out the math but it just got way to confusing for me. When would spirit take over intellect in terms of total mana as a holy priest, if it even would? My Theory is that with intellect you have a set number of mana, IE 15 per 1. With spirit you indefinitely regen mana while your in combat, thus making your mana pool larger than it actually would be.
So without gimping my SP, i would want to go with the most effective mana regen. When would Spirit>Intellect?
