It's well known that a person standing at range healing or dpsing has a 30% buffer in aggro generated before the mob will change targets... strangely, though, a shadow priest in my guild sent me a tell saying something to the effect of "dude wtf are you talking about this 30% aggro buffer? I pulled after 101%."

Now the question being posed: Does KTM show exact threat output, or modified threat output? Meaning: does it realize someone's standing at range and adjust their threat % accordingly such that when they hit 100% on the meter, in actuality they're @ 130% of the current aggro target? Or... would you actually see a 130% mark before a person is supposed to have pulled?

The aggro gain happened during Hydross, and I'm personally wanting to think that resetting aggro on transitions messed up the meter, but I'd like some more KTM savvy people to back my claims. :]

This is essentially how I was looking at it... I didn't think Kenco would have put in the extra work of writing range checking code.

Have you seen a ranged dps sitting at 115% or so before on a non-aggro-modifying boss? (Which I think displays the ranged person @ 100% and the tank @ something ~85-90 or whatever % 100/115 comes out to be :P)

It doesn't perform a modifier for people at range like you describe. Aggro Gain bar is 130% when you are at range.

Shadow priest threat isn't great on KTM atm. It's probably due to VE healing or mana gain, and interaction with silent resolve. Also Hydross threat wipes would contribute small inaccuracies of their own.

Thanks very much... I'll pass along the word.

This agrees with my experience on the matter too, aggro doesn't seem to be constantly reevaluated, but when it is - it bases the calculations on everyone in the raid at that moment in time, regardless of the melee/ranged threshold.

130% aggro ceilings are fairly artificial, these days. Shadowpriests, locks, and mages alike (I've never seen our hunters competing with MT threat) have all pulled aggro just after the 100% threshold. As alluded to, our MT/RL and those DPS have come to a similar conclusion that mobs are not reacquiring previous MT after RSTS abilities. Hydross, Tidewalker, and Gruul are all culprit of chasing ranged after RSTS hits.

And as much as I'd love to believe VE/VT threat is misunderstood and miscalculated. After doing Void Reaver (modified KTM) and hugging the aggro ceiling, reported VE/VT values are fairly accurate.

I also have a theory that Shadowpriests are more likely to be victim of the phenomenon because of the number of actions performed per second.

Long story short, it's been my guilds experience that passing #1 threat is, at best, gambling with your raid's success. 100% is the cap.

What exactly does RSTS stand for? I know it means an ability that's targetted on someone that's not the tank, more or less, but I never understood what the acronym meant.

If you think that is strange, last night's Prince in Karazhan decided to come over to the ranged group and slap a mage who was at 80% of tank's threat and then it went back to the tank.

I have never seen this behavior in KT.

KTM is usually spot-on, but last night on Vashj, I noticed some . . . inconsistencies. I don't want to go into any more detail, but has anyone else noticed odd ranged aggro behavior on this fight?

BTW, what's Void Reaver's ability called, is it "Knockback"?
