Unless someone can give me a good reason to, of course. But everyone's talking about what they will buy, and it seems like no one is talking about what they won't.
What I am talking about is this: [Gavel of Naaru Blessings]
Now, it seems like a really nice mace. The 464 healing really pops out at you and makes you go "Wow! That'll put me up to (insert large number here) healing!" Sometimes it's easy to be blinded by raw +healing numbers. They're often the first thing people ask for when they ask for a healer: what is your +healing?
However, the second thing people ask for is what your mp5 while casting is.
This mace has intellect on it, the only arguable contribution to your mp5 while casting. It has only 7 more intellect than [Light's Justice], and contains none of the +20 spirit of the weapon. It has 8 more intellect than [Shard of the Virtuous] and none of the mp5.
What the Gavel does have, however, is stamina. It has loads of stamina. Therefore, the question becomes this: what do you need more, mp5 or health?
At this point in my WoW career, I focus more on longevity than raw healing power. My HoTs get overwritten sometimes, and I do well enough as a buffer to spike damage. I am not trying to get off the big heals, just keep my HoTs ticking. Therefore, I need a constant supply of mana. I will never be outside the five-second rule, and I cannot get mana back from crits or heals on myself. I do not want to depend on group makeup to make myself viable for a long boss fight.
Right now, I am using a [Rod of the Blazing Light]. I see no reason to spend 150 badges on an item that will decrease my mp5 simply so I may boost my +healing and stamina. I'd prefer to save up for something else, thank you.
