Hi, I'm looking for some info on what kind of uptime a disc priest dedicated to tank healing can be expected to maintain.

Logs to look at would be ideal, if you have them.

not sure how much help this will be, but here's the parse from last week while in Uld 10

Mimiron hardmode
Freya hardmode
Vezax hardmode
yogg normal

parse.

the info seems to indicate 36% uptime on inspiration.

I dont spec inspiration we have a holy priest in our guild and his inspiration buff always seems up on the tanks no matter what I do so whats the point of me speccing it ? It doesn't stack as far as im aware.

However I think the other priest is about to go on a 2 week break so im gonna have to respec.

Note the uptime is quite a bit higher on the fights where tanks are getting directly healed throughout. Also consider the interaction between Inspiration and Ancestral Fortitude from the resto shaman, where gaining one will remove the other though it still would have had time to run out.

The tank vs raid healing focus will affect the numbers as well, PoH is nice for putting lots of Inspiration up on plenty of random raid members where it does less good than on the tanks.

For reference, one of our Disc priests had 71.9% uptime on Inspiration while primarily healing 3 tanks at Kologarn.

Thanks for all the information so far. Those fights are kind of hard to get what I'm looking for, though. I'm imagining in a best case it would be ideal for a disc priest to maintain inspiration a very high percentage of the time, but I don't know what a "high percentage of time" actually works out to be in the real world.

Ideal fights would be fights where one tank is taking most of the damage and the disc priest would be dedicated for the majority of the fight to that tank. (The closest I can think of in current content is perhaps XT hard, with the exception of pummel time.)

If you're dedicated to tank healing, shouldnt the uptime of inspiration be ~80%-100% except on Vezax? 36% uptime sounds more like the uptime of someone who's healing the OT or someone who's tank healing but focusing on shield spam.

yeah, my parse is definitely not dedicated tank healing. we cross heal quite a bit.

The correct answer is 43%.

This. If you're focusing on a tank, there's no reason a disc priest shouldn't keep inspiration up through the whole fight. Ideally anyway... for fights like Council, Hodir, Ignis, XT, Kolo, Auriaya... plus Sartharion and most fights in Naxx. Taking into account things like tank switches and phase changes where there might be a break in healing, like Mim or Freya or Yogg, or gimmicky fights like Vezax, you're going to see a bit of a dip in reality.

The only thing to note is that if a shaman's present, Ancestral Fortitude can kinda skew the parses. So the combination of Ancestral Fortitude and Inspiriation should ideally be close to 100% (or whatever's reasonable for the encounter).

That's really irritating that ancestral fortitude knocks it off.

I'd still really like to see some logs of actual fights, if anyone has any. I haven't seen many with very high percentages. Is it that in real raiding micromanaging the inspiration buff is not worth forsaking the other utility a disc priest can offer, or there are so few fights where you really get to just heal the tank constantly?

A flat 10% damage reduction seems like a pretty big deal.

I have checked on this earlier, before it changed to dmg reduction from armor increase. For example, we had a really big difference in damage on the main tank at hodir from one week to another. The first week I had been healing the tank and the uptime of Inspiration was pretty high. The week after it was a pvp-specced discipline priest who had healed the same tank and he then got inspiration just occasionally from the holy priest. But we weren't sure the big difference could be explained just by the uptime of inspiration.

I'm afraid I don't have so many new examples, I have been holy in many fights recently, but from last week I have Northrend Beasts, where I was on tanks all the time, but since the were switching between who was maintanking all the time, it's not a that good example.
Tank1: Inspiration 23,3%, ancestral fortitude 45,8%, total=69,1%
Tank2: Inspiration 29,8%, ancestral fortitude 24,5%, total=54,3%
So not so high I guess...

Now I found an old Hodir example, where I was focusing on the main tank: http://www.worldoflogs.com/reports/wabf ... 12&e=11442
There you can see that the uptime of Inspiration is 65,9% and ancestral fortitude is 24,5%, so then it sums up to 90,4%.
(Not so proud of my uptime of Weakened Soul though).

You should find some other examples if you check the same raid for other bosses, like XT-002 Deconstructor (uptime for I+AF >75%), Ignis (uptime for inspiration here is 70,5% and AF is 16,9%)

When I'm set on a single target I micromanage it. I sit there watching an SBF bar count it down. It's worth doing.

But do I intentionally juggle Inspiration across multiple targets beyond my assignment? I typically don't go that far, as it can put a strain on my GCDs and mana.

Inspiration competing with other buffs does suck. I'd wonder why for some fights my Divine Aegis uptime was significantly higher than my Inspiration. Didn't seem to make sense. But then you look to find an Ancestral Fort uptime of 50%+ on him.

Bottom line for me is I watch it like a hawk during the time I'm healing a given tank. But I'm rarely on the same target for every phase of a fight (or even within range), rarely healing him straight through without pause, and competing with other buffs. The dumb start-to-finish percentages can paint a worse picture than was actually the case.

Thanks for the info. That's sort of what I figured. I'd like another Patchwerk-style fight for some number crunching.

Algalon!

If you want to theorycraft on this, I would like to suggest a formula Dagma once mentioned for holy concentration.



Where n stands for the amount of heals on the tank you cast during the buff duration, and c stands for your crit chance.
For example, casting 1 heal on the tank every 2 seconds on average with 25% crit gives:
n = 7,5
c = 25%
Uptime % = 88.44%

If you feel like using this inspiration uptime as part of your healing strategy it may be interesting to investigate that function a bit
(in fact I'm working on it but I'm going very slow atm)

here's a parse from my last 25 man mimiron, normal not hard mode. i don't think hard mode is a good example, since you have to move so much there's alot of just PW:S/mending people and waiting on the druid to top them off because you have to move at that particular moment.

good for comparison since there's a lot of flash heal spam, a lot of tank concentration (especially the ranged tank in phase 3), etc. i'm at about 30% crit and 12% haste self buffed, don't know how those compare to your passive bonuses.
