Interesting read. I am bit confused about something, though. You stated:

“My talent build for tank healing focuses on propping up Nourish, Rejuvenation, and Regrowth.”

But then you state:

“The only change for me is that this heal will now be Nourish instead of Regrowth.”

If you are using Nourish instead of Regrowth, did you really mean to say that you are “propping up” Regrowth? When you heal are you keeping only rejuv and LB up then using Nourish? Or are you doing rejuv, LB AND regrowth and then using Nourish?

Thanks for your consideration.

Spirit is still a pretty useful stat to have as it increases your spellpower, and whilst innervate has been severely nerfed (tbh it was overpowered because we regenerated a bar and a half back), it could mean the difference between downing a boss and not downing them. My own personal opinion is that removing Living Spirit will only compound what is already a dire situation for us druids, and so we must try our best to preserve what little mana regen from spirit we can get – especially as Ulduar is no walk in the park like Naxx was.

Just because blizz nerf something doesn’t make it useless. Look at LB and Sydera pointing out that LB featured heavily in the Ulduar raid healing meters.
We just have to be more resourceful by being rebel like me

You’re right about nourish too. What annoys me most is that blizz seem to have forced it upon us restos, but being the rebel, I like to chose my own ways. Nourish hasn’t played that an important a role for me so far in Ulduar 25 simply because 1/ the spike damage means that other classes’ snipe heals are more effective because 2/ who has time to cast many HOTS then cast nourish when we’re talking about random raid damage of such high proportion? Nourish alone is useless in these situations.

Last night’s read on WWS (both mine and Arktos’, who kicked my ass on the meters) says that the biggest return on effort is Wild Growth, followed by (surprise surprise) Lifebloom. Ulduar healing is very, very spammy, and also GCD-constrained, so I might even revise my builds. It seems to be all about instant casts, and the amount of damage is such that HoTs are not going to overheal. I think it’s a mistake to over-emphasize Nourish, and I certainly saw that it my own numbers. My fellow druid, Arktos, was using almost exclusively Lifebloom and Wild Growth, with an occasional Rejuv, and that was really, really helpful for the raid it looks like. However, the biggest reason Arktos outplayed me by a mile was that Ignis kept killing me a minute into the attempts. It’s hard to put out much healing if you’re present for 27% of an attempt. I’d like to see if I can contribute a little more on tonight’s raid with a bigger focus on instants.

Last I checked, I was short of the 1 sec GCD with 290 haste on my gear. I haven’t geared for haste on purpse, so the extra 3% would be helpful. I might put those points somewhere else if I end up with significant amounts of haste on my gear just because of Ulduar itemization.

Got a question though. In build 3 you are are squeezing those extra 3% spell haste out of the balance tree. For how much spell haste are you aiming on your gear then? Together with GotEM and Ulduar gear you could get below 1sec GCD quick.
