Crit can be somewhat useful before you can get a decent amount of spirit, in combo with glyph of Illumination, but once you can start to get spirit on a large amount of your gear it becomes significantly better
"holy shock have like 25%+ crit bonus already".
This is news to me.
After digging around for this info in the web, I can confirm that Holy Shock do have crit bonus making crit based build redundant.
Thanks for the eye-opener EqualWin
It states the additional chance to crit in the tooltip. Also, crit is not very dependable as its rng and really has no added bonus. Haste is very good for us because it scales well with raid buffs and since we are complete hardcasters, it means more heals. Mastery is great right now because it simply is an added bonus to our heals while decreasing Dmg the raid takes, saving us mana. Crit isn't at the bottom because its necessarily bad, its just not nearly as good.
