Just trying to think of a way to do these style of fights better as an off tank.

Battle Shout spam should be superior to Sunder spam when you are only really getting rage from white hits and trying to pull aggro right?

10 rage for 55 threat / person * 5 People (unknown if it must be clicked off or not though) = 27.5 threat / rage / target

5/5 Defiance Sunder is 260 * 1.30 * 1.15 = 388.7 / 15 = 25.9 threat / rage, talented 32.4 threat / rage

Seems like it would be a decent idea to use battle shout to build off tank threat (sans talented Sunder) and a bonus is you don't have to worry about miss/dodge/parry and it is cheaper so you get a smoother threat curve as your ability is used more often. Assuming that battle shout reapplications do provide the same threat as the initial.

Thoughts?

It depends quite a lot if you really can use BS. We usually have Paladin + Warlock + few tanks / rogues in Broodlord tankgroups, so you'd probably be BS'ing only 3 ppl. On huhuran MT group we usually have MT, OT, Hunter, Priest and Warlock, so it'd mean from 2-4ppl depending if warlock and or hunter poisontank in close range...

So in theory, yes, but usually your group compostion is such that you have either shamans / warlocks / paladins in tankgroup who don't want to stay inside the BS range.

Would seem reasonable to get them to adjust positions though especially to allow better control over Huhuran especially... Broodlord not so much because of Blastwave.

Though it might be worthwhile to pick up a few points in the extended range talent.

Huhuran is high rage off tanking if you do it like we do: Switch very early in the fight and then switch every time the OT's stacking DoT wears off. We usually have about 3-4 switches before 30%.

Same here - assuming your tanks are familiar with their own aggro levels it is relatively easy for MT1 to simply stop attacking at around 4 debuffs and let MT2 overtake him. Keep doing this until around 32%, stop dps, switch tanks so you have a MT with no debuffs again for the enrage, then go full out dps.

I'm not really trying to alter the overall strategy on say Huhuran or whatever, just trying to find ways that are better to generate threat as an off tank in a generic sense, but Huhuran and Broodlord seemed decent examples.

Wrong title perhaps I suppose, sorry.

Regardless, is any information known about if repeated applications of battle shout generating the same threat?

I tried it a bit as a Hakkar tank but the results weren't very impressive, though that perhaps might have been the hunter overaggroing, though I am not sure, switched to a more standard sunder and bloodrage strategy and worked fine though.

I was thinking about this recently. I am glad to see I am not insane. It sounds like a good idea. (Switching more than once, not necessarily switching 4 times which sounds a little goofy)

Indeed, the battle shout should go to 55*1.30*1.15= 82.225 with def stance and defiance.
Applying it to 5 ppl would give 426.125 threat, which is 42.6125 threat/rage.
For 4 people buffed it is 32.89 (still better than improved SA), for 3 24.6675, which is worse than not improved SA.

So I think, if everybody of your party is in range, battle shout would be a very good tool to genereate threat if there is low rage available.
Problem is, the warlock in your party will most likely be out of range. Priest/hunter/shaman/paladin most likely as well.
The only ones who really should be within range are rogues and other melees. And as a rogue, I prefer an improved battleshout if available.

On a sidenode, is the warlock's imp affected by battleshout?

I believe Hunter's pets are, not Warlock Imps as they are generally phase shifted.

I did not include the defensive bonus and defiance modifiers as the information from Kenco seemed to indicate it was only base theat not modified by stance, I could be misunderstanding it however.

Same here as an OT, but I don't use battle shout, nor even sunder primarily, still rely on revenge/shield block, shield slam, hs and only some sunders, but with TF.

How are you using revenge while not the primary target?

On topic: Maybe use a Macro to switch between dual wield and Shield(Weaponquickswap recommended). Using an offhand certainly helps building rage faster.

Offtopic: If Hunter Pets are affected by Battleshout... I imagine a group with 4 Hunters+Pets in range to be by far the most efficient way to build aggro. Not that I can think of any use for that.

Now the question is, is battleshout affected by def stance and defiance or not?
It isn't very clear on Kencos summary.

Stand a bit closer and get slept and have someone specifically assigned to cure it off you asap, gives a bit of extra rage

Based on the wording battle shout would not get the bonus for defiance as it isn't an "attack."

Has anyone tested this?

Yeah, but look at Effect 1.

Pretty much what we do.
Also, as an OT for Huhuran, an effective way to sustain rage is to ask for a quick cleanse of Wyvern Sting when you know you can handle the 3k damage it deals. The damage taken gives a nice amount of rage to climb back up for the next switch.

We just switched to the "sacrificial lamb" strategy after a while. Much easier.

Athough, you'll just have to deal with it again on Gluth, so maybe that's not to be encouraged anymore.

I keep seeing advice for specific circumstances, eg: dispel wyvern sting etc.

While those are valid (and nesscessary sometimes!) ideas, it doesn't really address the generic problem of how to efficiently spend the rage you are getting with the goal of generating threat. Sunder just is not that great at developing threat with only a S/S setup, and I did try adjusting to two-hander and windfury in defensive to improve threat generation and it did help a lot. Somewhat dangerous to eat a few hits without a shield though sometimes unless you are using KLH or Invunlerability pots and know precisely when the transition will occur. Definitly going to have to run a few experiments to see which sort of strategy works better. Good advice though. Somewhat stuck as a 31/1/19 at the moment so SS is a bit off as I am behind a few long standing tanks that are already protection.

Abilities should generate threat, though the amount for Battle Shout probably needs a nerf, though the only "nerf" to battle shout tanking that I know of is to the Twin Emperors initial proximity threat bonus being reduced so healers would outpace the tank on the caster Emperor quickly (or something like that).

Nefarian phase 1 would be another one.
Single tank spamming battle shout near the throne while casters AoE made the fight trivial for us.

Its just about crazy enough to work, by jove!

I just duel wield in def stance when I need to build threat. But then, I'm fury.
