i dont know if the matter has been discussed in other threads, but i'd like some opinions on which spec is better for PvE healing. Right now i use http://thottbot.com/priest/t#ELMFQq9kL8/uxOc and my stats are 1970 spellpower (buffed with Inner fire and Divine Spirit), 18120 mana, 283 mp5 amd 16% holy crit.
I know that the whole WoW community still views the Disc priest as the PVP/tank priest, but after having played both specs, i can say that Discipline is slightly better overall, and that is because of the Rapture-Penance combo that makes Penance restore 120 mana per tick and effectively making Penance's mana cost ~180 mana (provided you have Improved Healing in the Holy tree) which is way too low for a spell that heals for 9000 average and applies 3/3 Grace on the target as well as having a good chance to crit and thus not only heal for more but also shielding for 30% of the tick that critted. (whew i'm out of breath)
please contribute your opinion on the matter.
