I got ilvl456 and im on almost 9220 with some greens still. Should we aim for more then?

Because not all fights have magical damage. For example, the Will of the Emperor Encounter has little magical damage, but much of the aoe damage is physical. Unglyphed Dprot would be worthless on that encounter, whereas glyphing it would give you some resistance at least.

Not all physical damage is melee, there have been encounters in the past where aoe damage is physical(for example in t13, morchoks stomp was physical, as was all the AoE in blackhorn p2) and it looks like there are a handful encounters in t14 where this will be true. Just glyph for those fights.

I agree that it can be useful, just extremely situational.
So I guess, /agree? Well said.

Anyone tested Glyph of the Battle Healer - Spell - World of Warcraft in raids?
What about reforges, mastery still the strongest and way to go?

A question in regards to Seal of Insight - is it worth going into melee and leaving auto-attack on for regen? I've found it helpful in dungeons, but going into raiding I'm wondering if it's a silly decision. It seems logical with the opportunity for regen, but I'm usually a priest and just wondering

As i think, it is. If you manage to stay in melee zone during the whole encounter, regen from Seal can give you approximately 15% of your total manaregen (according to my logs, and it can be even more), which is pretty useful, i guess.

Is Holy Light/beacon swapping still our most efficient way of raid healing? I feel like I'm struggling to keep my mana up in raids but that might be due to gear or some other reason. Did they make some change to Holy Shock to be used in a different role besides burst HPS? I am using Holy Prism which seems to be a very mana efficient heal to be used on CD.

I'm getting [Relic of Chi Ji] when the Faire comes on Sunday. Is anyone able to do the maths to work out if [Price of Progress] or [Vial of Ichorous Blood] is the best choice to go with it?

My feeling is [Price of Progress] because I really hate use trinkets, but will still go with whichever is the most MP5.

Spi mana regen is = Total Mana *0.02 +(1.1287*SPI*in combat regen%)

[Vial of Ichorous Blood] - 706,8 extra spi, gives 399mp5
[Price of Progress] - Internal cd 50s, assuming it goes off once per minute that's 424mp5, might get lower if you are unlucky.

I am running Spirit > Mastery > Crit > Haste at the moment (and was running Mastery >= Haste in Dragonsoul) with decent success. On current gear levels secondary stats do not stack to high enough amounts that would make Haste difference noticeable, while Mana is still an issue and just increasing your throughput is not good enough in my opinion. I suspect this trend will continue for a while and even if Haste gives you more control over damage intake especially in first few weeks of heroic progression (This is from perspective of semi-hardcore guild, top50 might think otherwise).

I've been working on some spreadsheets for holy healing and at my gear levels with mastery efficiency around 75%-80%, mastery gives around me slightly below 2/3rd of haste throughput while increasing mana efficiency. Take it with a grain of salt tho, as its still work in progress.

That said stacking mastery is still suboptimal on AoE heavy fights (feng comes to mind).

Healing has usually been a bit of an odd duck when it comes to stat values for throughput because of the different demands and playstyles of healing.

In terms of statistical gains though:

1% haste = 425 rating.
1% crit = 600 rating.
1 mastery point is 600 rating.

So 100 haste equals .235% more throughput
100 crit provides .166% more throughput
and mastery, assuming the conversion functions like Cata where 1 point is actually 1/8th the original amount (12% for IH), means it's 100 mastery for .25% more throughput.

Haste's throughput value of course assumes chaincasting, but the real value most healers like it for is quicker spells for clinch moments.
Crit is always on, and unlike haste does not increase mana consumption too.
Mastery is likewise always on and doesn't use extra mana, but it also doesn't always work because it doesn't transfer through Beacon of Light. It also doesn't work on ticks of Holy Radiance. I don't recall whether it works on Light of Dawn.

Last I heard Spirit's regen value had intellect in the equation, but that seems to have been taken out and everyone is saying 100 spirit = ~56 MP5 during combat with whatever class's version of Meditation. At the moment I can't verify the exact number, especially since it's listed differently between here, the druids, the shamans, monks, and priests all saying something different. Either it's different for each class or people are getting the numbers screwed up. Possibly both.

I haven't yet seen the mana values of each of our spells, but I'm still searching around. If someone would post them that would work too so we can maybe show, among other things, how haste affects our mana expenditure and what amount of spirit might counter that
