Perhaps if you just keep stacking spirit you'll be good? Maybe there will be a spirit cap where your mana regen will be higher than the actual heals you cast?
I just find it kind of strange that there's really no way for holy priests to receive mana anymore. Shadowfiend has been nerfed so much it's not even worth using it. Hymn of Hope has never been good. So let's say I go oom in the middle of an icc encounter, what do I do?
I'm trying to conserve mana with heal and stuff, but I always turn out oom.
Tips would be cool.
