Curse of Weakness

It is well known that 14 AP (attack power) translates to 1 DPS. It is less known that AP increases are calculated before speed modifiers, so haste multipliers increase your AP proportionately. This means that while more AP increases youre base damage, haste will increase your damage exponentially.



The same applies to bosses as well. What this means for raidbosses, who get anywhere from 30-50% speed increase is that AP Debuffs are far more effective on raidbosses. You will get nearly 3-5x the return off Curse of weakness and the like as you will on regular mobs.



When considering the returns off Curse of Weakness, the base 350 attack power seems a bit low. This translates to about 29.1 DPS. Most people don't consider this worth wasting the curse on. Now look at the same returns with 50% haste rating (such as prince during phase 2). Total AP reduction now comes to 58.33 DPS. With 2.5 second attacks pre-haste, this means 150 dmg per hit. Over 30 seconds, this means you will prevent about 1750 dmg.



All in all, I can't recommend Curse of Weakness unless you are having extreme trouble keeping your tanks up. It simply doesn't mitigate enough to be worth the loss of DPS or the curse of elements/shadow
