I've seen a lot of hpallys when they have good enough to gear to completely dump spirit and gem pure mastery, sometimes even dropping socket bonuses so they can gem more yellow mastery gems. On the other hand i've seen a lot of good pallys gemming almost full spirit. I personally sit on around 15k spirit and output a nice amount of healing and have nice mana regen, it works for me How much spirit do you guys run and why? (add information such as ilevel and the trinkets do you have)
