Benediction over heart of the crusader/ full PoJ= bad mana will never ever ever be a issue with the new prot divine plea. and having heart of the crusader is nice incase the ret pally and or ele shaman are no present/dead.
seals of the pure over divinity? i still dont see dps catching up to tps at this stage in the game. and with some of the bigger hitters in ulduar i dont see 5% healing taken a waste.
