Druids aggro generation, unlike warriors, is solely centered around the idea of the more damage you do the more aggro you generate. In this thread, I wish to explore how much aggro each move does then analyze on the basis of time and rage the aggro a druid generates.

Druid Aggro Multipliers
Bear Form Multiplier - Druids by solely being in bear form generate 1.3x more aggro than normally.
Feral Instinct (Talent) - Druids can spend 3 pts into Feral Instinct for a 5% increase in aggro generation for each point for a final multiplier of 1.15x.
Special Moves - Maul and Swipe generate 75% more aggro than autoattack does resulting in an additional 1.75x multiplier on them. (unknown for Lacerate)

Druid AutoAttack
A druids base weapon is 2.5 seconds with 54.7 DPS with an increase of 1 DPS per 14 Attack Power.

Druid Damage Talents
Naturalist - Increases all damage by 10%
Savage Fury - Increases the damage done by Maul, Swipe, and Mangle by 20%

Druid Special Moves
Maul (15 Rage/10 Rage Talented) - Deals 100% Weapon Damage + 176 Damage giving us a formula of the below
Aggro_Maul=A*(1+C)*(2.5*(54.7+P/14)+176)*1.1*1.2*1.75*1.3*1.15
Aggro_Maul=A*(1+C)*(P*0.61669+1080)

Mangle (20 Rage/15 Rage Talented) - Deals 130% Weapon Damage + 234 Damage giving us a formula of the below
Aggro_Mangle=A*(1+C)*(2.5*(54.7+P/14)*1.3+234)*1.1*1.2*1.3*1.15
Aggro_Mangle=A*(1+C)*(P*0.64271+812.6)

Swipe (20 Rage/15 Rage Talented) - Deals 84 Damage to 3 nearby targets w/ additional 0.07 damage per 1 Attack Power
Aggro_Swipe=A*(1+C)*(84+0.07*P)*1.1*1.2*1.75*1.3*1.15
Aggro_Swipe=A*(1+C)*(P*0.24174+290)

Lacerate (15 Rage/13 Rage Talented) - At 1 Stack deals 31 Damage (40.3 w/ Mangle) per tick every 3 seconds for 5 ticks (15 seconds) At 5 ticks its 155 Damage per tick (201.5 w/ Mangle) and w/ Naturalist 170.5 per tick (221.65 w/ Mangle) so this works out to aggro generated by Lacerate per tick as
Aggro_Lacerate=L*31*1.3*1.1*1.75*1.3*1.15 (w/ Mangle)
Aggro_Lacerate=L*115.9783625 (w/ Mangle)
Aggro_Lacerate=579.8918125 (L=5)

Attack power has no added benefit for Lacerate and aggro generated might be different since says causing a high amount of threat (needs testing to determine if its actually different).

A = Armor Mitigation
P = Attack Power
L = Lacerate Stack
C = Crit Rate

Make notice both cat form and bear form mangles currently can stack resulting in two 1.3x multipliers for damage on bleeds.

Maximal Single Target Threat Rotation
12.5 Second Rotation works out fairly well for being potentially possible to pull off while closest enough to the LCM for all the various numbers involved

5 Mauls

Global Cooldown Moves
1. Swipe
2. Mangle
3. Swipe
4. Swipe
5. Swipe
6. Mangle
7. Swipe
8. Lacerate

Total Aggro Moves
5 Mauls (50 Rage)
2 Mangles (30 Rage)
5 Swipes (75 Rage)
4 Lacerate Ticks (13 Rage)
Total Rage = 168 Rage

Threat Generated
Threat = 5*A*(1+C)*(P*0.61669+1080)+2*A*(1+C)*(P*0.64271+812.6)+5*A*(1+C)*(P*0.24174+290)+4*57 9.9
Threat = A*(1+C)*(P*5.57757+8475.2)+2319.6
Threat Per Second = Threat/12.5 Seconds ~= A*(1+C)*(P*0.446+678)+185.6

Rage Required Per Second = 168 Rage/12.5 Seconds = 13.44 Rage/Second

FWIW, there's an old thread about this, but it didn't see too much discussion.

Yeah, I want to work out the exact details of what it means but figure I would start with just the basics then work it out. My next plan is to generate the same formulas for a warrior for comparison value. Basically had to start somewhere and figured before getting into working out the supposed maximum single target aggro generation cycle I would set down the formulas I've worked out so far here to get comments back on.

One thing, I need to rework the equations to take into account damage mitigation.

These warrior numbers might be slightly off so would need a warrior to check over them to see if the various mechanics are correct.

Warrior Aggro Generation
Sunder (15 Rage) - 301.5*1.3*1.15=450.7425
Heroic Strike (196+(W+500)*A)*1.3*1.15
Devastate (15 Rage) - (27+(35*5+50%*W)*A)*1.3*1.5
Shield Slam (20 Rage) - (307+(430+S)*A)*1.3*1.5
Revenge (5 Rage) - (417+110*A)*1.3*1.5

W=Weapon Damage
A=Damage Mitigation
S=Shield Block

Heh I will say 2.8k Attack Power is a little on the high side for tanking gear. My current tanking gear puts me at 1314 Attack Power completely unbuffed while I have 19282 Armor, 25.51% Dodge, and +46 Defense (110 Defense Rating). There is improvements of course to be made in my gear but nowhere the amount to get 2.8k Attack Power.

Something to test would be whether Mangle gets the 1.75 threat modifer or not. I've seen a couple of brief tests posted (mangle then get an unarmed party member to pull agro punching) that suggested that Mangle doesn't get the same modifer that Maul/Swipe do significantly widening the gap in terms of agro/rage of Maul versus Mangle. Still leaves it as a great rage dump and a better alternative than swipe against single targets (maths in the Druid Talents are up thread if curious).

We have both Druid and Warrior tanks and in a rage limited situation the Druid makes more threat (fights like Jin'do where the boss hits like a pansy or trash pulls). In infinite rage situations threat generation seems to be more on par using Vael as an example. The difference is Warriors have a bunch of quick consistant moves for threat generation and for the Druid it comes in big 2.5s long threat clumps, if a Druid gets 2 or 3 mauls parried/blocked in a row you'll have a threat gap but if they don't get any blocked/parried you'll see them well ahead of where a Warrior would be (till they get some blocked then it evens out again).

For a raid buffed Druid tank you're probably looking at 1000-1300AP for your base generation. My ideal geared druid tank has ~750AP unbuffed and with Battle Shout, GoA, SoE, Mongoose, and Giants ~1200AP (~32% critical strike). After mitigation you're looking at ~800-1000TPS (threat per second) which is equivalent to a Warrior of the same gear level.

In rage limited situations the Druid should only be using Maul and Mangle, if rage is flowing faster than you can use it on those two powers you can rage dump with Swipe similar to a Warrior doing so with Heroic Strike. The threat per rage for Maul/Mangle is much better than any series of moves a Warrior can put together. I don't have my numbers on this computer but from what we looked it its 1.5-2x the threat per rage over a Warrior depending on the rest of the factors in the situation.

Yeah, I will change mangle. I need to get some testing in later on that and Lacerate.

1300 AP seems ridiculously low. All the druid tanks I've run with have substantially more than that and they haven't been raid buffed.

Browsing around on thott I can come up with a set of blues:

With:
- Blessing of Might
- Battle Shout
- Strength of Earth
- Mark of the Wild
- PW: Fortitude
- Strength Elixer

- +6 stats chest enchant
- 70 AP weapon enchant

That druid has:
- 2400 AP
- 13000 Armor
- 11300 Health

I would assume getting into lvl 70 epics will easily net you another 400 ap

Cryect are you in that gear on live, or beta?

(I was also going to point out other stuff, like mangle... but it all got talked about as I read down :( )

1.3k AP (unbuffed) isn't really that low for bearform tanking gear and this is on Beta at Lvl 70. My Cat Form gear is just under 2k AP unbuffed.

13k armor is really low for tanking you don't go for AP when your tanking you go for mitigation and defense.
