If you rupture, then vanish, does the succeeding ticks still generate aggro to you? Or has the debuff been disconnected from your aggro when you vanish?

Exe: Had a fight with Hakkar where I grabbed aggro less than 10 seconds after vanishing. It was a mostly alt run, the tanks were alts, and one of them was very new to playing a tank. So, I just assume they I overtook their threat from the previous MC in those 10 seconds. That would seem practically impossible to me, as I had only done a SS/1pt SnD/berzerk/SS/SS in that time. But, I had done a 5pt rupture prior to vanishing, waited for full energy and then started attacking again. If the rupture damage was being attributed to me during the entire time, it'd make a little more sense.

It seems such a minor thing, but I've been using rupture more and more since reading a thread here awhile ago, and have noticed I can overtake many better geared rogues on fights that I can manage to use it. I'd like to know for sure the mechanics of the aggro that it generates for future reference, and was curious if anyone had done testing or had additional info regarding rupture. It's just one of the aspects of the class I never looked into. But, would like to know if I should weight it the same as a 900 damage eviscerate or similar.

Yea, and if no one knows the answer, I'm gonna see if I can get someone to do that with me. On one hand, I seem to recall being out of combat any time I'm vanished, even if the rupture ticks while vanished. If the damage was attributed to you, I would think it'd put you in combat. On the other hand, maybe when your back in combat the resulting ticks while in combat are then assigned to you as aggro, just not the ones while vanished.
Same thing for deadly poison or other DoTs, and for hunters with feign death. Just would be interesting to know how the game handles aggro when your in an 'null' state such as being feigned or vanished. Like, does it save all the damage done while vanished and then all of it is put on you when you come out of vanish, or not.

Two things:

1. I'm fairly certain ticks of Rupture after vanishing would generate threat still. Don't have any hard evidence, but it would logically be this way.

2. Chances are if you pulled aggro 10s after Vanishing, your Vanish failed or did not register properly and you did not drop out of combat (and thus did not actually wipe your threat).

I have tested HoTs affects when in/out of combat and found that a HoT will not contribute any agro towards its caster unless the caster is in combat.
Though the rules may be different in this case, I don't find it unreasonable to assume no agro is generated while out of combat.

Possible test?

Naked level 60 Rogue with highest level Rupture and level 1 Dirk

Warrior.

Warrior builds up about 260 threat.

Rogue sinister strikes once, and hits rupture (keeping in mind the Rogue's -20% base threat generation). This will be about 100 damage for the sinister strike, and 255 damage for the rupture.

Does the mob turn on the rogue at the moment of rupture, assuming the warrior is doing nothing else, or after several ticks of the rupture have resolved?

The way DoTs work for other classes is you get threat for each tic. It should work the same for a Rogue.

As to the OP who pulled aggro after 10 seconds, it seems that Vanish failed to remove you from combat (possibly an unlucky combat pulse).
