It only applies to the direct damage spell because it's only a -100 threat to scorch fireball frostbolt and arcane missle, if you read the set bonus is mentions nothing of ignite. Would be cool if it was -100 threat off each ignite tick, but thats not the case.

Only frostbolt and Scorch get -100 threat from NW 3 piece bonus straight up.

Arcane Missils gets -20 threat on each missile pulse, and Fireball gets -20 threat on the initial hit, and then -20 threat on each tick of the DoT. So it's not very much use for Fireball, as it very rarely gets to tick for every tick of it's DoT in a raid setting.

The NW 3 piece bonus kicks in after any other aggro modifiers according to KTM theory, so makes it a bit more powerful than you would think once all the modifiers kick in.

The dot being the useless fireball dot or the dot being the ignite if it crits?

The fireball dot. Not that -20 on each ignite tick would amount to anything either.

His question was one he and I were discussing in regards to a mage who had the sustained ignite tick on Loatheb, then the spore buff expiring, and the ignite tick continuing for insane damage amounts.

I pretty positive we answered it tonight when I had the ignite tick and then missed the next spore buff, and continued receiving a 4k ignite tick for over a minute and a half or so and didn't get aggro.

That's 180k in ignite ticks alone o.O

Ya, it looks something like this

The thread wasn't about warrior aggro mechanics, it was about a threat modifier at the beginning of an ignite stack continuing on when the players(mage's) threat modifier changes.... referring directly to the 100% threat reduction given by the spore buff on Loatheb. Ofcourse ignite ticks always generate threat, but if the threat is reduced by 100% it doesn't really matter what the tank is doing as long as he has auto-attack on now does it. I don't really see what your post has to do with the topic.

His posts NEVER have anything to do with the topic, im shocked more havent noticed heh.

Having done loatheb last night, I can say with a reasonable degree of confidence that ignites threat DOES change dynamically when people pick up the spore debuff (ie even if you have a ignite running before you get it when you pick up the debuff your threat goes to 0 from any subsequent ticks) as we had mages miss the debuff and pick up a slightly later one while owning the ignite stack still and they wouldve pulled agro straight off the tank if it didnt. Unfortunatly i have no dps/ktm to show you this in action tho, was too excited by the huge difference the darkmoon faire buff is, saved me a shadow pot :P

sorry guys :(

threat is calculated at the time the damage lands.

cause your damage is multiplied with your threat modifier at that specific time.
as Tel just said: if you have the spore buff there is little to no threat generated.

This would support my thinking on the situation, that the threat modifier attached to ignite is set in stone from the mage's threat reduction when he BEGINS the ignite tick. Your scenario would also coincide with my scenario which was about the opposite, I begain the ignite tick with the spore buff and then missed next spore buff while ignite tick kept going for 1.5 min and I did not pull aggro, even though I was about 200k damage above rest of raid group.
