For awhile (3 months of raiding) i thought that gemming for int was the way to go for disc priest, i mean int gives so many groovy little door prizes like, a bigger mana pool which in turn leads to more mana regen if there is replenishment in the raid(replenishment gives mana back based on maximum mana size) and for Rapture which gives 2.5% of maximum mana when a shield breaks if you invest 3 skill points into it, int gives crit, and it gives a little mana regen too. However i met a fello disc priest today who had gemmed everything with crit and she/he (who can tell these days) told me that when healing an mt mana is never an issue. Her/his mana regen was only in the 200s where as mine was in the high 400s. Having a bunch of crit meant she just needed to shield and penance the tank and that got her/him through all the bosses in uludar 25 man. She/he was in full t8+ and a bunch of other such ilvl 226 items. Now my question is should crit be the way for disc priest to gem their gear or is int still the way to go?
Any assistance for clearing up this confusion is appreciated.
P.S. Any critiques or advice? Thanks
