Im a level 31 priest, and im wondering which would be better for dungeons holy or disc? Id also like to know which one is best at 85 for heroics, and maybe group healing.
for leveling, disc. attonement once you pick up the talents (very soon) will probably have you doing as much dmg as the mages whilst still healing
for 85. TBH i love disc too much, so id have to stick by my 20" guns
they havent got the burst AOE capability like a holy priest (PoH with an immediate CoH is pretty awesome) but for sustatined output, yes they have very good group healing capability
personally i keep the evangilism at 5 stacks and only consume the buff when i switch to a "regular" spell, like flash/greater or PoH.
reason being is that the mana reduction applies to holy fire / smite and penance. which apart from shielding and a PoM are my main single target heal, the mana reduction is very welcome. it also increases the damage done of the holy fire and smite which is also an increase to healing done by the spells.
when combined with the glyph to increase smites damge on a target affected by holy fire its powerful. raid buffed im about 11k spell power and with evangalism stacked to 5 smite is crit healing about 32k, smites about 29k
Disc and Holy both have their own perks tbh its a personal choice that only u can make but failing that go HOLY cause were pro lol
Split the difference, off spec holy and try it out, use disc to quest and heal till you find one you like better.
Edit: check out attonment in your disc tree for smite healing.

If you go Smite healing, you can just DPS to keep your group up and not waste time standing around.
At lvl 85, smiting is mostly used to get Arch Angel for times of high damage and not so much as proper healing.
