Math Behind it (Establishing Reduction)

Trash Mobs:

Important Notes:

All values are verified using a hunter and Beast Lore.

Testing done on normal level 80 mob and an elite level 80 instance mob.

Same mob used for all 3 test sets in each case (hunter used freezing trap while I used dual spec to test different values)

When comparing to the -575 Value, a fulled talented Curse of Weakness, Vindication, Demoralizing Roar / Shout or a base Demoralizing Screech should all fall to within a fraction of a percent for comparable effectiveness.

Test Case 1:

Mob: Infesting Jormungar

Zone: Storm Peaks

Mob Type: Normal

Base Stats:

Melee Damage 421 - 587 Damage

Demoralizing Roar - Base Value of -411 AP

Melee Damage 362 - 528 Damage

Variance in minimum hit - 14%

Variance in maximum hit - 10%

Demoralizing Roar - Talented Value of -575 AP

Melee Damage 339 - 505 Damage

Variance in minimum hit - 19.5%

Variance in maximum hit - 14%

Test Case 2:

Mob: Azure Mage Slayer

Location: Heroic Violet Hold

Mob Type: Elite

Base Stats:

Melee Damage 569 - 792 Damage

Demoralizing Roar - Base Value of -411 AP

Melee Damage 489- 713 Damage

Variance in minimum hit - 14%

Variance in maximum hit - 10%

Demoralizing Roar - Talented Value of -575 AP

Melee Damage 458 - 681 Damage

Variance in minimum hit - 19.6%

Variance in maximum hit - 14%

Conclusion

Given that the minimum and maximum values scale slightly differently, it still appears to be at least a 12% averaged reduction per hit on the base line ability. This appears to increase to a 16.75% averaged reduction at a fully talented shout / roar.

Raid Boss Example:

Test done on Mexxena in 25 Man Naxxarmas. Talents refer to the adjustment made by increasing the power of the effect with Improved Demo Shout or Feral Aggression. Vindication did not provide a AP Debuff at time of Testing and Hunter's Carrion Bird was a max of -411 AP equaling it to the Base Reduction field.

Normal Value 19,547 - 26,828 Damage

Base Reduction of -411: 17169-24450

Talented Reduction 1/5: 16978-24259

Talented Reduction 2/5: 16787-24068

Talented Reduction 3/5: 16596-23877

Talented Reduction 4/5: 16405-23686

Talented Reduction 5/5: 16220-23501

This shows a minimum hit difference of 17.1%

This also shows a maximum hit difference of 12.5%

This is an averaged decrease in melee damage of 14.8% at full power (-575 AP)

An important note here is the Raid Boss follows the same pattern as normal non-raid trash, but you don't see quite the same drop off in terms of Damage Reduced.

Trash showed a 14% variance in maximum hit and a 19.6% difference in minimum compared to the verified values above of 12.5% and 17.1%. Even as this seems to be the case in this test, your looking at a less then 2.5% difference between how -575 AP effects the Raid Boss compared to normal trash.

Simply by applying Shout at base rank (- 411 AP) you reduce the maximum hit of the Boss by 8.9% and the minimum hit by 12.2% or 10.55% averaged.

By adding a talent point to the Shout this changes the base reduction in maximum hit by a very small percentage, my math gets me .8% and the minimum by 1.2% or roughly 1% averaged. This average reduction continues all the way to 5/5 talented, there is a slight curve to the reduction which makes it just under 1% thus shown above which is why fully talented the reduction is 14.8% instead of 15.55% when speaking in context of this particular NPC.

It is important to note that all NPCs are slightly difference, but you can expect a roughly 10-12% reduction in melee damage at -411 AP and ranging from 15-17% at a maximum value of -575 AP.

Special moves such as Thorim's Unbalancing Strike derive a larger percentage of their damage from the NPC's Attack Power, thus you should see larger reduction in power, possibly as high as Ghostcrawler's claimed 50%. This makes Attack Debuffs a very important part of any 25 Man Raid (Since they are balanced around being there) and a considerable survivability boost to any 10 Man format raids.
