Ultimate Guide to Aggro

Summary:
the values for abilities (I will recheck these)

6) Healing, "you gain x ___", etc
Each point of healing, when completely unmodified by talents, gives 0.5 threat. Replace the proof for (2) by the second person only healing.
Note: overhealing doesn't count, only the actual amount healed. This is easy to demonstrate.
Abilities that put "you gain x mana" in the combat log give 0.5 threat per point gained; life is the same. Examples would be drinking potions, but not natural regen, or the Shaman's mana spring totem.
Abilities that put "you gain x rage" in the combat log give 5 threat per point gained. However, this is not modified by warrior stance. Such abilities include bloodrage, improved blocking talent, unbridled wrath, and 5/8 Might.
Like healing, these only give threat if you are below the maximum.

Summary:
for every point of damage healed you get 0.5 points of threat i.e. 100 damage healed gives 50 threat
Same ratios apply for mana gained
For every point of rage gained (through abilities) you get 5 threat not changed by stances and only happens if you are below maximum threat i.e. not being attacked


7) Explaining damage to heal ratio
I stated that in my tests, each point of damage by the warrior took approximately 4 points of healing by the priest, for the priest to get aggro. Here's how:
Warrior in defensive stance, with defiance: 1.45 multiplier
Gaining aggro from Warrior: 1.1 multiplier
Priest with discipline: 80% threat
Healing: each point gives 0.5 threat

Together, 1.45 * 1.1 / 0.8 / 0.5 = 3.9875. Pretty darn close to 4.


8) Threat from pulling?
There is no threat associated with pulling. The smallest amounts of threat we could generate drew aggro from a body pull, no matter how long we waited after the pull. However, there are advantages to having the tank pull, as explained in the next section.


9) Taunt Updated Jan 19
Casting taunt causes three effects.
A) The warrior is given as much threat as the person who currently has the mob's aggro. Obviously if the warrior has aggro, this will do nothing. Also, this effect will not lower the warriors threat. For example, if player 1 has 100 threat and aggro, a warrior could have 105 but not aggro; after taunt he would still be on 105 threat.
B) The mob recalculates its actual aggro target. If the warrior was on the mob's hatelist before the original aggro target, the mob's actual aggro target will switch to the warrior. Otherwise, the mob will remember it's original target.
C) The normal taunt debuff. The mob is forced to attack the warrior, even if the warrior is not its actual aggro target.
The threat that the warrior gains from (A) is permanent, regardless of the outcome of (B). Note that it will not necessarily give the warrior the equal highest threat on the mob. If player 1 has 100 threat and aggro, Player 2 has 109 threat but not aggro, and the warrior has 0 threat, then the warrior is given 100 threat, not 109, so he could easily lose aggro to Player 2 after taunting.


10) Implications.
a) Let the tank pull! Then he will be first on all the mobs' hatelists, and his taunts will always return aggro to him.

b) Given that targets at range will only draw aggro when they have more than 130% of the mob's target's current threat, it's important for a tank to keep the mobs well away from the casters. If a healer does draw aggro and you taunt it off him, make sure you also move it away.

c) Heroic Strike should not be used as a primary threat ability. Suppose you are tanking a level 62 mob. Let's give him 8,000 ac raw, and even assume he has 5 sunders stacked, for 5750 final ac, so he will take 48.89% of damage. A 15% crit rate is balanced by the 10% penalty to damage in defensive stance, and a 10% chance of a glancing blow chance for 50% damage. Then you can expect the 138 damage from Heroic Strike to contribute 67.5 damage on average, for a total of 212 unmodified threat. This is still only 82% of the threat a sunder would give. Even with a 1.3 speed weapon, you will still do 94% the threat of sunder per time interval.
Best practice is to spam sunder, and use HS in between to soak up excess rage.

d) Revenge ftw. You can expect to do about 345 unmodified threat with Revenge, including damage, against the mob in the example above, which is exceptional for the low rage cost, even throwing in 10 for a shield block. However, there is a rage cost of shield block, in that you will block more attacks, so take less damage, so gain less rage from damage. Two blocks for 180 damage and you can say goodbye to another 4 rage.

e) Demo Shout ftl. Demoralizing shout does one sixth the threat of a sunder. Even spammed in defensive stance with defiance, you're doing no more threat than 42dps on each mob. Besides picking up whelps in Onyxia and tanking panthers in the Panther boss encounter in ZG, I can't see a compelling reason to use this.

f) Shield Slam ftl. Given the 6 second cooldown, there is no improvement in threat per second by using shield slam. With shield slam: 3 sunders and 1 shield slam every 6 seconds. About 212 threat per second, unmodified. With the 30 rage from the shield slam you can cast 1 sunder and about 1.2 heroic strikes, assuming you have the talents (which you would with any shield slam build), and are losing 3 rage per Heroic Strike from lost white damage rage (i.e. assuming 90 modified damage per hit). The 4 sunders and 1.2 heroic strikes every 6 seconds gives about 215 threat per second.

The only improvement is if you are spamming both sunder and HS, and want even more threat. Suppose we have a 2.0 speed weapon, HS spam and sunder spam. That's about 280 unmodified tps. Changing one sunder for a shield slam gives us 318 unmodified. However, the same effect would be achieved by changing to a 1.4 speed weapon and casting HS more often. And these values aren't taking into account autoattack damage, which makes the margins comparatively smaller.
g) There's no amazing super secret randomized blizzard aggro algorithm. The concepts are simple and the values can be fitted with nice numbers. Even formulas for threat-reducing knockbacks can conceivably be worked out, if threat values are carefully monitored.


hopefully this helps you peeps. don't worry new aspiring warriors when you have played a bit this will help not scare. thanx to those peeps who helped with the data you know who you are.
