For our guild we just rely on a disc priest to cover infest. His job from phase 1 - phase 3 is to keep every raid member in the raid shielded. With this strategey the infest DOT will never kick in. So far the raid healing is minimal except for the transition phase(pain and suffering).

I'm actually thinking of speccing into empowered touch/living seed as I find myself tank healing alot.

If you're casting rejuvs after infest hits, you're already too late. Those rejuvs won't tick until infest ticks 2-3 times, putting you even farther behind. Everyone should be loaded with a rejuv up before Infest hits. Consider unglyphing Rapid Rejuv if this is troublesome with short duration hots. Then, just WG a clump of people when infest hits and SM/nourish anyone who needs a spot heal.

You can also layer on lifeblooms onto people whom you know will need a little extra hp boost when infest is soon. If timed properly, the lifebloom pop will heal them up to full without needing any other healing.

Just to support the above, in 10s I primarily roll rejuv on the non-tanks, WG as infest hits, and swiftmend or nourish as necessary, then repeat.

Trees are really good here for transitions and the Valk phase when you need to move to avoid Defile.

We actually just downed him last night(finally) and we had the same healing comp as what you say you have available. Tree, Healadin and Priest. Had the priest in as disc because as has been said, the bubbles completely negate Infest. Most of P1 I would just have hots rolling on the tanks and a couple melee that tend to pull some of the ghouls with splash damage. Also healed up anyone that accidentally wandered in front of a shockwave while trying to dump their disease(name isn't coming to me atm).

Going to and during the transition phases I blanketed the raid with rejuv, hots on tanks as well as spot healed people that stood in front of the raging spirits(see a trend here?). Having the raid blanketed here helps a lot since there is constant AoE going out and if one of the spirits hits a non tank you can toss out a quick SW to save them. Make sure you've got hots rolling as you run back in after the transitions(both of them) as infest will be coming and not everyone will have bubbles due to the AoE damage they've been taking.

And really that's pretty much it for the fight. Blanket the raid and keep hots on the tank to cover damage spikes and make sure you heal the frostmourne target in P3 as they can take quite a bit of damage before they go into the room.

That's how I did it last night anyways, hopefully it helps you get through it too.

Druid and the tank healing.

On the topic being lately discussed. We had something like 25-30 attempts on Saurfang 25m hardmode on Thursday. The healing setup was the following: 1 disc priest, 2 resto druids, 2 holy paladins and 1 resto shaman.

What we did on the first attempts was basically having both paladins beacon one mark each while continuing to heal the tanks. The rest of the healers picked one (assigned before the pull) mark later into the fight. This proved nothing more than a waste of time. We had either tanks randomly dying to spike damage or the marks dying to I-don't-know-what (could be other healers slacking).

After a several minutes of discussion, it was decided that one of the resto druids will heal the tanks. On the 7 pulls we made with me healing the tanks, there was no single tank death before the mark targets dying or the adds gibbing someone or any other sort of thing that would cause a wipe being called on vent. The only tricky part for me was the tank transition when Saurfang had 60+ rage. I've tried my best to watch DBM timers to have Regrowth landing at the same very moment transition was going to happen. Thus I ensured having a hot on a tank and (possibly) negating some bit of a first hit the tank would get. If he dipped low for some reason, I usually had my Swiftmend or NS up. Then I, depending on the situation, either had Nourish being followed or Rejuv and slow stacking Lifebloom. Spamming Nourishes even with huge overhealing proved to be the most efficient thing to do to avoid random two-shot.

Now, surfing the logs of that evening, I can see the following healing done by spell: (the logs are closed so can't provide the link)
1. Nourish (36.3% of total healing or 2374707).
2. Rejuvenation (19.8% or 1294597 healing).
3. Living Seed (15.6% or 1022878).
4. Regrowth (12.0% or 787066).
5. Lifebloom (9.6% or 629463)
6. Other (6.6%)
All the attempts showed the similar healing percentage with small mistake.

The Living Seed healing is quite impressive as you can see. I had Nourish and RR glyphs. On the incomming Monday attempts, I think about throwing off some haste/spirit offsets and getting haste/crit ones to increase the healing output via more Nourish/Living Seed output. Still not sure if it's worth the spellpower and mana regen loss though. If you have any ideas how to improve the standard raid healing gear or maybe even the rotation I use to make more/better tank healing, please post.
The easiest and probably the fastest way to get out of the Frostmourne room is to basically spam heal Terenas inside. You open with Regrowth followed by Rejuvenation, then you slow stack Lifebloom while chain casting Nourishes. The only trick: keep the Lifebloom stack till the opposing guy starts casting. At this point let the stacks bloom and hit Swiftmend. That will give the burst enough to get Terenas to full hp again so he can still hit harder. Really had no problems inside besides one time when I tried bashing the cast.

From my experience, the marks dieing to I-don't-know-what usually happens when a mark gets Boiling Blood as well, case in which it's very very hard to keep up by 1 healer only, need people to notice it and assist immediately.
As for healing done by spell, here's our log for the 25hc kill if it helps: World of Logs - Real Time Raid Analysis

I used Rapid Rejuvenation glyph instead of Wild Growth, but the other druid did not. I had 4th mark, and constantly assisted with Regrowth and Rejuvenation on all the previous marks, as well as dropping as many HoTs as possible on the tanks as well. The tanks were mainly healed by our paladins, with beacons on first 2 marks, but they need HoTs on them whenever possible, and require some spot healing at high blood power. We also assigned the priests to the last 2 marks, so they could assist with shielding the previous ones.

Heroic Saurfang 25

We had 2 Holy Pallys, 1 Tree, 1 Disc Priest, 1 Holy Priest, 1 Resto Shammy

Basically until the 4th mark went out we had the pally's on the tanks. Once the 4th mark went out the holy pallys swapped to each having 1 mark beacon and 1 mark as focus. They were able to fully take care of 4 marks. Once they swapped off tanks, the shammy and disc priest focused the tanks with my druid HoT's. The 5th mark went to the holy priest, and I took the 6th mark. I was also trying to keep up Rejuv (RR) on the tanks, 5th mark as well as those with boiling blood. At the very end, the marks become more important than the boiling blood targets and that is important to keep in mind. I made sure to have Regrowth, 3LB and Rejuv on my mark and used nourish as needed on my 6th mark focus.

Thats just how we did it- and it was centered around working with the healing comp we had. Hope maybe it helps someone! Here are the logs if anyone is interested: World of Logs - Real Time Raid Analysis

RR
I did not use RR much for regular kills- but now on heroic I am finding it useful. For instance, throwing it on the Vile Gas targets for Rotface and Festergut allowed for quicker ticks to get those people back up to full health faster. A PW:S + RR on vile gas made them no problem. Additionally- the faster ticks during Marrowgar's bonestorm were pretty nice to get people up faster. My guild just started heroic modes last week- so I have been doing alot of experimentation with swapping glyphs between attempts- so my observations are just based on that. What are other people's thoughts on RR for the 'higher damage' heroic modes?

In 25-man, I use RR and 4T9 at Saurfang and Valithria, no RR and 4T10 everywhere else. In 10-man, I play around a little--I definitely like RR at BQL because the fight lends itself so well to mindless 5x1 spam. At Sindragosa, I've done it both ways, either is perfectly workable. All in all, you can probably comfortably use or not use RR for the whole 10-man zone--using it means you're going to using Rejuv almost exclusively and won't quite have perfect uptime, not using it frees up GCD's for other things and generally leaves people with better coverage if you have range issues or other interruptions. Only major exceptions are that I'd always use it at Saurfang/Valithria/BQL, and never use it at LK.

RR is also good on Putricide. There's close to zero raid-wide damage and you mainly heal tanks or stabilize the Gas Cloud / Volatile Ooze / Unbound Plague targets. In that case you have quite a lot of GCDs to spare. Revitalize procs on the Abomination are quite handy when learning the encounter and the best way to force them is glyphing RR and rolling Rejuv (possibly Wild Growth if other healers do their job good enough) on it.

Here we go talking about glyphs again, I think out of 12 pages maybe 8 of them are about rapid rejuvenation! (Which by the way I only use for 10 mans and sometimes the trash before 25 man Marrogar cos I forget to switch back :P)

I was wondering if there are any trees out there who have healed lich king heroic on 10 man yet? I've only managed to kill it playing my offspec, was just curious if disc/paladin is the only healing composition being used throughout the community.

I'm keen to try it but I think the general consensus is that it can't be done with any other combination.

Your thoughts?

Couple things of note on these recorded kill logs:

• In the two-healer kills, all the healers are using Val'Anyr
• There seems the be an anomoly with the three-healer log, as healing done drops off to zero for over two full minutes in the middle of the encounter.

We've been working on HLK10 with a Pally/Druid/Shaman combo for the last few week with little success. As an experiment, we had someone swap to an lesser geared Disc Priest alt (Some ICC gear instead of mostly full ICC10 Heroic). It was absolutely astounding how much the shields nullified Infest and turned something that seemed so chaotic into something a lot more managable.
