Update with some demo shout evidence:
Here is a video of a warrior kiting adds on razorgore with demo shout (courtesy of
Graves):
https://www.youtube.com/watch?v=qVeIEDZkXrsThere are 3 ways that demo shout threat could work:
1) Threat is divided among ALL targets in combat, like healing threat
2) Threat is divided among all targets HIT by the debuff (~42 divided by number of targets affected)
3) The same amount of threat is applied to each target hit with the debuff (~42 threat to each target)
In the video we see that the warrior auto attacks the mob to get initial agro. After that, the warrior kites the mobs in a group and uses demo shout and piercing howl to keep agro over the healers. We also see a second warrior kiting an even larger group of legionnaires.
I think we can definitely rule out #1 from this video and I don't think nost is using this method at all.
So, the next question is, would it be possible to hold agro on this many mobs if demo shout threat is divided among all targets hit? We can see that the warrior does receive some healing so healers are definitely causing threat on all targets. Is it a matter of healer threat being divided among such a large number of mobs that demo shout still works even with mechanic #2?
He isn't exactly spamming demo shout, seems to only use it 1-2 times on each platform.
I can't make out the numbers on the threat meter in the video but it looks like several healers have AT LEAST over 1000 threat on razorgore. Assuming that the threat meter properly divides threat among all targets, the healers have at least 1000 threat on the mobs kited since the beginning of the event. It's hard to tell but it looks to me like some healers have over 4000 threat.
I don't think it is possible for a warrior to be kiting mobs like this if demo shout threat is divided among all the targets hit.
