Where (in terms of either of the previous diagrams) do you have the spriests stand to accomplish this, and has that been effected by the change in the slash arc? Sorry if this is an ignorant question as I have unfortunately not passed kalecgos yet.

Shadow Priests in soakers group are indeed extremely useful to top up the soakers, however, we had our SPs soaking the slash as well. Pretty much we had everyone except 1 raid healing shaman and the melees soaking some slashes, with rotations in and out depending from burns etc.

However, as far as healing goes: for 2 tanks strat users at least, I assume soaking group never get more than 3 stacks of the Meteor Slash debuff. There is no need for healers to top up a group with Shadowpriest (bar people with burn in that group) after the 3rd stack is applied. They won't get damage until 48 seconds later anyway and that can be easily be left to the Shadow Priest to compensate with VE, and maybe a chain heal from your raid healer (if you use a shaman for that). Infact, the only time a group with SP will actually need focused healing is after slash #2 hits, and just to ensure that they won't get killed by slash #3 12secs later. Healing power can hence be focused on the tanks and burning people then.

Here's our WWS for yesterday's kill if it may be useful to anyone:

Any news on Brutallus' armor value yet?
I would guess it's 7700 unsundered, but having reliable numbers might make it easier to optimize melee-gear for the fight.

It's 7685 undebuffed. I tested it on live and test, and there's calculations in one of the rogue threads based on a TClap with FF up that confirm it.

I would also like to know his armor value.

To me it 'feels' a little higher than normal.

I guess the drop in dps over most BT/MH fights is a little from that and a little from losing 5% hit due to Sunwell Radiance buff.

[edit] Thanks to above poster, got in before I clicked submit

Sunwell Radiance (Sunwell Radiance - Spells - World of Warcraft) does not affect your chance to hit the mob. It increases the chance a mob will hit the tank, and reduces the chance a tank will dodge his attacks by 20%.

Because he has 7700 armor and almost everything in Hyjal/BT has 6200.

I already pointed this out on the first page of this thread, but theres still a lot of people that dont know that he has in fact 10.5M HP and not 10M. You need 29 166.666 raid DPS to beat the enrage timer, not 27 777.777.

A lot of guilds are failing the enrage because they think they have enough DPS to beat it when they actually dont.

Doesnt seem to make that much difference on most encounters though. I read a lot of them at are Brutallus' armor level too, unless I'm reading incorrect info.

High Warlord Naj'entus: 7685
Supremus: 7685
Shade of Akama: 7685
Gurtogg Bloodboil: 7685
Reliquary of Souls: 7685 (apart from the phase 1 which is 0)
Illidan Stormrage: 7685

Has anyone figured out how Stomp works with armour buffs?

Does it reduce armour bonuses like Ironshield Potions and Devotion aura as well?

My tanks say Ironshield are unaffected.

Thats funny because almost every WWS parse says 10 M health.

Check the total damage done at the bottom, it's 10.5Mil, WWS is probably bugging because it doesn't display 3 numbers properly, as the highest HP total for any fight before Brutallus has been around 9.5mil on Kael'thas.

Also, we can know his exact HP, because when he resets, he gets healed for his max HP: 10,502,917.

You know what's even funnier? The first WWS link I could find scrolling up had 10.505.526 damage.

And their log of the night had two wipes at 10.436.740 and 10.201.434 damage.
And checking half a dozen logs from the WWS search has values of 10.504.000 to 10.508.000.

It's definately 10.5 M HP, and that 0.7% wipe must have been painful.

Check the total damage dealt out at the bottom.

Using the WWS from a few posts up:

Raid 10 505 526 28 393

Looks like 10.5 million to me.

If you look at the sum of the "Dmg Out" column, it adds up to 10.5m. (for ours this week 10,510,169 to be exact)

WWS just truncates it to the nearest million once you reach double digit millions for mob HP I guess.

For those of you killing brut, who do you give your shadowpriests to? Our tank healers were going oom at around 1 minute until enrage (with flask, oil, food, and potting on CD) and I'm wondering if it would be worth it to give them one over one of our caster groups.

We give them to our tank healers and mages. We have enough dps when our warlocks are lifetapping/mana pots so no reason for them (or hunters) to need a spriest.

We usually run with a single Shadow Priest because their personal DPS is pretty poor compared to the alternatives at high T6 levels of gear, and that guy is in a caster DPS group. Your healers should be able to manage their mana for the duration of the fight without outside help. It's only 6 minutes, and honestly any mana-using class should be able to figure out how to time their pots and other cooldowns to sustain for 6 minutes. If your healers run OOM with max consumables at 5 minutes...well, they need to do better. Even with fantastic gear I'm gassed by the end of Brutallus, but if I play right and don't get totally screwed by the RNG with my pots I'll manage.

This will largely depend on the following:
-How many Healers? 6, 7, 8, 9?
-How many shadow priests do you have?
-Do you have a ret paladin?
-How tight are you on the enrage timer vs how close are your tanks to dieing?
-How good are the dps'ers that you are potentially giving shadowpriests to and how much of a gain will they see from increased mana?

Those are probably some of the major contributing factors. Analyze some WWS' of kills with a raid makeup similar to your own or change your raid makeup to provide better synergy. Generally I would follow the principal that no matter how high your dps is, a dead tank is a dead tank. That said, once your healers can keep the tank alive for 6 minutes, they need precisely ZERO more mana and you need to push dps. Try and figure out ways for various groups of players to be less dependent on shadowpriests, then give the shadow priest to whoever actually requires it.

Hopefully I'm giving you enough help without just giving answers away (there are more than one correct way to do this). Play around with the encounter and see what your raid needs.

From what I can tell from our wws reports, Burn ticks for 10x100, 11x200, 11x400, 11x800, 11x1600 and finally 6x3200.

I cannot speak for other healing classes, but as a priest you could use your cooldowns very efficiently so that mana would not be a problem.

Shadowfiend x2 (early so it is up at the end)
Super Mana Potion x3 (combined with an alchemist's stone is even better)
Dark Rune x3
Inner Focusx2 (In conjunction with a clearcast is good for at least 1 tick outside of the rule which raid buffed should be around 1k mana)
Bangle/Earring combination (could equal a lot of mana with procs combined with spirit clicks)
