This fight is...clunky. It requires finesse and coordination, but until you reach it in heroic mode (which I have not, and few have), it can be brute-forced through with only a few adjustment wipes.
The biggest, most essential part of this boss is the distribution of Permafrost. As a healer, this is obviously not your concern unless the boss burrows. My guild DPS'd the orbs until they were low, then attempted to Death Grip them into position. Though possibly the best plan, it is still rather unwieldy as the orbs start floating away and up as soon as they are released, making early Death Grips ruin positioning.
Why is it important to position Permafrost? To prevent burrowing. The adds are able to burrow, but not if their hitboxes are completely covered by the Permafrost. And by completely, I mean absolutely no portion of their hitbox can be uncovered or they will burrow. With the adds, this means that they burrow, then repop after more adds spawn, quickly overwhelming your off-tank.
Very important for healers (and everyone else) to know: never stand in front of the boss! He cleaves, and it hurts. The tank has priority on movement. You make way for him, not the other way around. Another thing to watch out for, as well, is that the main tank will periodically get frozen, basically stunning him and locking him in place. Keeping HoTs stacked and controlled cooldown application (with conservation for the last 30% in mind) will allow your tank to survive. As well, watch for any raid members with the Penetrating Cold debuff, as it will knock off a 2k+ of their HP each 3 seconds.
When Anub'arak submerges, the whole raid needs to clump together on Permafrost. This will prevent a large amount of damage coming from the submerged Anub'arak (his hardest hitting attack cannot penetrate Permafrost) and allow for controlled AoE of the scarab adds. Watch for the large ice spikes that form up around your group; as soon as they pop, move to the next patch of Permafrost. They do no damage, they simply signify that Anub'arak has broken that patch of ice and it will despawn, leaving you defenseless. He will "pursue" raid members, but so long as everyone is clumped up in the middle of a patch of Permafrost and not on the edges, he remains ineffective. After the fourth submerge, he enrages and it's a wipe.
At 30% life, Anub'arak will cease burrowing and cast Leeching Swarm. This is where it becomes tricky, if somewhat boring, for healers. I had to all but stop healing except for occasional HoTs on the tank.
What? But why? Shouldn't the last 30% be harder?
It is, it is. But it is harder because it requires a large amount of control, and HoTs are somewhat of a loose cannon. You see, Leeching Swarm takes 10% of remaining life (not total) from the person it is applied to, and it is applied to the entire raid, to a minimum of 250 health. That means the lower people are, the less they heal the boss for. You want to juggle your raid at about 50% life to avoid deaths from Penetrating Cold, with only your tanks at max life. Since adds stop spawning at this phase as well, all remaining adds should be burned down to spare your OT's life requiring max fill. If you have multiple Restoration Druids, one or two max should use HoTs to counteract the swarm. Otherwise, all straight healing spells should be used, and you should be ready to cancel those heals at a moment's notice by jumping, hitting a cancel macro, esc or moving. I quite literally did almost no healing due to our raid having seven healers for the fight and other Druids covering the HoT portion. This is a little frustrating, but as Heroic mode will be draining 20% of remaining life, I have a feeling things will be a bit more active.
Well, that's the fight! Good luck, and my the loot gods smile upon you. Also, watch out for Death Knights who pop Path of Frost too early or Shamans who just have a sadistic desire to watch you break your bones on what should be a forgiving pool of water.

Argh I'm so frustrated. We took near two hours to get past the Twins tonight because the server/instance lag was impossible (5 second instant casts are not fun) and eventually got them without hitting the enrage.
Got to see Anub'arak a couple times but the lag didn't improve and eventually we just gave up when an instance server reset was announed. Hopefully it will all be fixed for tomorrow night.
I thought it was really interesting how similar and yet different this fight is when you think back to the Anub'arak in Azjol Nerub.
Were you ever successfully able to prevent Anub from submerging? We stopped the adds from going under quite successfully but no matter how well we laid our permafrost down, Anub would always submerge.
It's worth noting that permafrost does NOT stop Anub'arak from burrowing. Only his adds. His burrows also act as an enrage timer. A fourth burrow causes him to enrage when he un-submerges. Good luck!
No, we never successfully managed to keep him from burrowing. However, that's also because we didn't cover the floor properly with ice. Even one missing patch will allow him to submerge, unfortunately. :(
As far as normal-mode Anub goes, once he hit 30%, I was stuck casting a couple of Nourishes and that's about it. We run with three resto druids (obviously), and only one could really HoT without threatening to heal the boss. That didn't leave the other two much to do but really pick our noses. /sadpanda
Our guild found it easier to just have the raid spread out when Anub'arak burrows. It's easy enough to off-tank adds on one patch of permafrost while the raid DPSes them down.
Anub'arak will only follow one person at a time when he's submered, and the spikes go very slowly at first. If you just have the one person running around, avoiding permafrost and raid members, you can save your permafrost only for when the spikes speed up and can't be outrun.
(This will also prepare you better for HM Anub'arak, where (apparently) there are only 6 floating permafrost orbs.)
This is on 10-man, haven't ventured in to 25-man Anub'arak yet.
@Drotara - thanks for pointing that out; everything I had read prior said it was possible. /angryface
We have to problems:
The miniadds leave many dots in the raid so some players end with a 16k each 3 sec debuff and they eventually die from it.
Boss is hitting our MT very hard, about 32k each 2 seconds. He is a full Ulduar 25 warrior. If he gets unlucky with parrys he dies instant.
Does anyone have the same problem?
@Cibo
If people are getting stacks of the de-buff, it's either their fault for not kiting around the perma-frost. Or, it's the DPSs fault for not taking them down quick enough.
I don't see how your tank is getting hit that hard... full Ulduar 25? Is he defense capped?
Oh, I forget... Anub does NOT cleave, in any mode.
Hi Bell, I'm a fellow Resto Druid (/cheer)!!
I saw that on your 2nd latest post you mentioned at the end that you had 2 man healed Anub on ToGC10.
I was wondering if you could give me any tips on healing this in p3. My group got to Anub with 40 attempts remaining (we're bad at Faction Champs :( ) and after about 30 wipes due to mindless slacking and sorting out what our final tactics were going to be, we actually reached p3. I had about 5 attempts at 2 man healing this with a holy priest, and I found it extremely difficult. I was getting out just below 6k hps but couldn't handle the AoE on 10 players and they would die one by one, making the fight last even longer and the healing required even more.
So I was just wondering if you have any tips, whether you HoT the raid or spam nourish, or how you assign the healing (with AoE, Penetrating Cold and 2 Tanks), or anything else.

Ps. First time on your site, love it though, keep up the great work!
Anub on ToGC10 is much the same as normal in p3. If you have rejuv on all your raid they just won't die (assuming a reasonable level of gear). They will just have to accept that their health will hover between 1-3k. So long as you're on the spot with the refreshes it'll be no problem at all.
