ll gear now has a stat called "spell power"
there is no talent that gives healers more +healing from spellpower or anything like that.
Blizzard has severely increased the coefficients from Healing spells in WotLK.
Currently the reported modifier when spell power gets run through a healing spell is 1.8
Currently in Mangos, the healing spell doesn't have this multiplier.
Maybe i'm wrong but
