What about replacing Nourish completely by Regrowth?
The direct heal of a glyphed Regrowth should be higher than an untalented (ET) and unglyphed Nourish. If Regrowth is a viable go-to heal in case of an emergency (of course not for "real" tank healing) it wouldn't hurt as much to spec out of ET.

I'm going to try this out for our ICC raid tomorrow night. I think that its a good place to sacrifice 2 talent points for the benefit of picking up ET for a stronger Nourish.

I don't have any mana issues now, so I doubt the loss in regen will make that big of a difference.

Yes but paying 30 frost emblems for 22 spellpower is kinda the last item i want

It's also a very safe buy - you won't find upgrades to this slot in ICC.
Personally I'm saving my badges for now, content is too easy and badges are still scarce. The value of 4T10 is quite questionable, although picking up the 2 haste pieces is probably a decent purchase as well.

It is if you have broken 4PC T9 already. Plug numbers into Wrath Calcs and how much healing the 2PC T10 does. You read the bonus and think "wow, that really looks good!". Then you actually see the numbers. It was about a 3.3% healing upgrade to WG alone, if I would have replaced my gloves and shoulders with T10, 251.

Are you saying 2T10 is bad cause it breaks 4T9? I tend to agree, and I think 4T9 will not be replaced in 5X1 fights at all.
Thing is that while Rejuv healing tends to vary a lot from fight to fight, WG hovers around the 20-25% mark. The added stats from wearing 2 277 items plus the set bonus may outperform 4T9 when healing is more evened out.
In the end, you have the buy SOMETHING. The idol is good because it's a sure bet, a clear upgrade that won't be replaced. [Belt of Petrified Ivy] is a very good choice if you're keeping 4T9. Trinket on the other hand is weak if you're sporting 2 solaces - which was the clear go-to item from the ToC loot lists before 3.2 was released (it's nearly always wise to go for the trinkets because you have 2).
Like I said, I don't feel particularly inclined to buy anything right now. Too many open questions - how useful will 4T9 continue to be? Did they really not fix 4T10 (and yes, I consider a POM-like rejuv to be a bug)? What slots did you manage to upgrade to 264 before the hardmodes are out? These will affect what pieces give the best upgrade when you need it.

I was also looking into more Haste/Crit items instead of spirit. It would lower my SP by a very little bit, and with 2x Solace, the regen is not an issue. I mentioned that I was keeping 4PC T9, so the extra boost in crit is more than enough to make up for Spirit loss. As for badges, I'll say it again. 310 Badges to get 4PC T10 without a major piece such as the Chest/Helm/Leggings. I also suggest on holding on badges before you make the move to T10. I wouldn't buy the first piece you get, because it may just be aweful, and you would just go with 5PC random drops, and only 2PC Haste T10.

To the contrary. The healers job is 2 things. Keep up the raid from regular boss mechanics, IE - Damage. The second is to pick up other players mistakes, IE - Void zones and fires and add aggro etc. There are preventative measures of not getting 6 marks, like increased DPS, increase range spread, more disc priests, etc. BUT 6 marks does make healing the biggest of the raids issue. One of them dies - 2 million health. More Mark uptime etc.

If all strategies are executed correctly, content would be farm from day zero. My guild got 7 marks our first Saurfang Pull, and 6 marks and like 85 energy on our 2nd kill. My guild is great, we have a lot of strong players and strategies. We have had insanity, and not by luck, but more than a few times. I lost our Immortality run myself on Faction Champions, the only person dieing the entire instance. I am not bragging my guild up, I am just saying even well progressed guilds make mistakes and don't execute strategies 100% efficiently. It is the whole raids job to make up for inefficiency, but more often than not, it is put on the healers in the end to keep up, like 2 mistress's or a long volcano up-time, or two black orbs in the white group, etc.

In situations like this, it is NOT our fault that we would wipe, but we CAN prevent it by stepping it up. If you get 7-8 marks here, or even more than that, no it is not ideal and not good, but at that moment in time, healing is the greatest of the raid's issues. It will continue to be this way until the end of the expansion.

I agree that the value of 4T9 has been little addressed. I, like many others, chose to lose 4T9 in order to reach the new haste soft-cap using a 18/0/53 build. I'm particularly interested in the prioritization of early ICC gear upgrades with respect to re-gaining 4T9 vs. 14/0/57. Hamlet's spreadsheet and my past combat logs (pre-3,2 with 4T9) confirms that re-gaining 4T9 (at least for my past healing roles) significantly outweighs the buffs to Nourish from ET, but 14/0/57 also brings a significant raid buff, which is difficult to compare & contrast. My gut says that re-gaining 4T9 should be my 1st priority... anyone else give some thought to this?

I see your point entirely, but coming from a guild that got its face raped by the encounter week 1 with an average of 5 marks and then stomped all over it in 2 attempts week 2 with a 3 mark kill, there was such a difference made by ranged not getting hit by the adds / mobs being kited properly that the extra healing required by Mark was not needed. Great healers can certainly give you an edge in a fight where you're not executing (and trust me, as a member of a guild that made no attempts into deep heroic ToC25 I don't really consider us top-end executors but rather fun-loving consumers of content), but the Mark mechanic is one that really penalizes healing marked targets. As a healer my job in that fight is to maximize my throughput while limiting whatever incidental damage I can get by drawing blood beast aggro and not running away from them properly. The healing component of the fight is pretty straightforward for a tree - HoT the DoT and stack the tanks. True you can brute-force the fight by just healing through marks, but there's a reason you get an achievement for killing him in under 5, because the primary mechanic of how the fight gets out of control is due to poor management of Saurfang's energy.

All guilds progress through mistakes - the last thing I'm doing is lambasting that. But the original question was how to handle the massive amount of healing in the Saurfang encounter when you're at 6+ marks, and the honest answer there is to have your ranged DPS and healers get the hell out of the way of those damn beasts, not "heal through it", although you certainly can do so. I just don't want to see the guy beat up and rip apart his spec / gear when what's really killing his raid is a DPS who is getting lit up by blood beasts, creating quicker marks, healing Saurfang more, and making a healer's life miserable.

There's leather version: Professor's Bloodied Smock - Items - Sigrie ; you shouldn't fight over the cloth one.

e: ok, just noticed that was a badge item. In that case, "there's a leather drop you don't have to compete for, so you probably shouldn't spend precious badges on that."
