Holy Paladin Mastery, is it really that bad?

I know that for my holy paladin that I go for Intellect> Spirit> Haste> Critical> Mastery. That set up seems to be the accepted best way to go, but I like to think about other options. Could Mastery end up being our best stat (if we're able to get a ton of it?).

What does it do?
Our Mastery is Illuminated Healing. At level 80 our direct healing spells will give a shield that absorbs damage. It lasts for 15 seconds (as of Patch 4.1), it starts at absorbing 10% of the heal, and increases at 1.5% per point of mastery (also as of Patch 4.1). Essentially this replaced Sacred Sheild for holy paladins, and I find it to be an interesting mastery compared to other healers.

Why is it so bad for us?
There are a few reasons. First, the sheild isn't terribly powerful. Absorbing for 10% of a 7k heal is only 700 damage absorbed, and that's pretty lackluster. Second, in comparison to Haste, Mastery appears to be very weak. To give you an idea, If I have a Shadow Priest, Boomkin, or Elemental Shaman in my heroic group I am sitting around 30% haste. That's right around where my haste was at in Icecrown. Heals are faster, the global cooldown is smaller, and Holy Radiance ticks more often. A lot of positives going on, all at once. Mastery isn't really keeping up.

What to do now?
The buffs to Mastery in 4.1 are going to help it out. Currently it is pretty even with Critical, so I would gague the buff to push it behind haste. I want to see if it can pass haste, and maybe even spriit. If the shields can become powerful enough to prevent us from casting as many heals, then we won't need the mana regen from spirit because we aren't casting as often.

So, I plan to head over to the Public Test Realms. While Blizzard is still testing for patch 4.2, I'm going to copy my paladin, and make a premade one to see how powerful Mastery can be. I'm going to gem exclusively for it, gear and reforge for it, and test my skills as healing with it. I'll be sure to record my numbers on recount, and I'll report my results as soon as I am finished.

Hypothesis
Everything is better when you have a ton of it. I hope to find that with a ton of Mastery you can be completely viable. If I am wrong, well it wouldn't be the first time.

Reforging Mastery or Haste

Now that my priest is level 83, I've started to think about what stats I want to prioritize for him. I know that critical rating is at the bottom, and that I reforge crit whenever it is on an item, but I am not sure about whether I should prioritize haste over mastery or vise versa.

I know that haste is needed and it's great, but I'm starting to think that I should go for mastery almost exclusively. Here's what I figure; I am rarely overhealing with more than 20% of my heals. Mastery is only third in terms of the spells that overheal. This makes me feel that the extra healing added from mastery won't add to the overhealing and will isntead provide a significant percentage of my overall healing.

Right now Echo of Light is only contributing to around 10% of my healing done. Since this is going to be free added healing, boosting it to provide more output should help it to move closer to 20% of my healing. On top of the added boost to output, the extra mastery will allow me to move on to heal another target sooner. I know that my last heal applied a significant heal over time, so I can move on to the next target.

That's how I'm think about things so far. I think that I'm going to gem for a combination of Intellect and Mastery, and I'm going to try to acquire more peices with mastery and reforge for it whenever I can. We'll see how this works out, as I am sure that I will probably revert to choosing haste to be number one after some more healing on my priest.

The new healing model

I will start by saying that I have really enjoyed healing on my priest and paladin. Now here is why.

The introduction of Heal and Holy Light as the medium efficient heal. This change has really changed how I have appraoched healing. I have a choice to make. If a tank is near half health do I use Heal because it's cheap, or do I use Greater Heal because they might die if I don't top them off soon enough? If a dps just took a huge chunk of damage do I use Greater Heal to get them to full health, or do I use Flash Heal because the sufficient heal won't get there in time?These options are a welcome change from the previous model of healing. (these apply to paladin just insert Holy Light, Flash of Light, and Divine Light respectively)

The new mechanics for priests and palains. For my paladin I really like how Holy Shock is the go to spell because it will buff the other heals. With the four peice set bonus on my teir 10 a Holy Shock critical makes Holy Light cast ridiculously fast, which is very cool. And I really like the options I have once I get 3 charges of Holy Power. Do I use Word of Glory now, or save that instant for when I won't have time to cast something?

For my priest I have enjoyed how Chakra has been working. Certain cases are better for corresponding Chakra states, and there is a decision to be made there as well. Surge of Light procs are a nice way to save some mana (I just wish it had a higher chance to proc), and like my paladin I really like the healing mastery bonus.

Mastery has turned out to be a very nice change. For my paladin I add some extra mitigation (which explains why Sacred Sheild went away), and for my priest the added heal over time helps me heal someone and not have to use a wastful heal to "top" someone off. Balancing how much mastery I go with, and making sure I still have enough Haste, Spell Power, Mana, Spirit, and Crit is a nice added bit of depth to stat choices.

So all in all I am very pleased with all of these changes. I know that a lot of people are not very pleased with these changes. To those people I say "QQ Moar!" The game is changing, and healing is changing with it. Hop on and enjoy the ride, or role a dps.

Reforging...

With the new patch hitting the servers today a new way to customize gear comes with it. Reforging, is a new tool that will let players pick a stat (ie. haste, crit, etc) on their gear and turn 40% of that stat into a more preferred stat. On both of my healers, this looks very appealing.

For my paladin I can turn some extra spirit into haste or crit, or I can make some of that extra crit into mastery or haste. I am not entirely sure how I am going to tackle this for my paladin, but I am thinking that crit is going to be more attractive for me.

For my priest, I've decided that haste is going to be very attractive. Not only will it help spells like Renew, and my mastery heal over time, it will help make the (very) slow Heal a little less slow. More Heals, will increase my chance for Surge of Light procs, and of course a smaller global cooldown. So haste is looking like a good first choice. So what I've decided with regards to Reforging I am planning on taking items that have crit and adding haste to those.

For my second choice, I am really liking mastery over crit right now. Crit is always unreliable, and only provides more overhealing. I won't need to rely on it for procs (like I did before 4.0), like I will be on my paladin (Holy Shock procs are nice). Which makes me think that mastery is going to be a nice stat to go with.

The Holy mastery will allow my direct healing spells to add a heal over time onto the target. You might not think that this is that great, but this is what I am thinking. Say I heal someone who just took a 6.5k hit. I heal for 6k, and apply the heal over time on top of that. This way the HoT will heal the remaining health preventing me from feeling a need to cast another heal that would then overheal. So if I can make this heal over time stronger, I'll be able to add a nice health cushion to targets, which I think will help out a lot.

So with regards to Reforging, I'm going to take items with Haste, and turn the Spirit on them into Mastery. I will warn you, though, Reforging can be very expensive if you decide to reforge all of you items at once.
