In the most recent 7.1.5 hotfix applied on January 31, 2017 Blizzard has changed Kingsbane so that it no longer double dips from Agonizing Poison.

This was a bug that needed to be fixed but it also represents a sizable nerf to the damage of Kingsbane.

Depending on the amount of mastery that you had Kingsbane was doing anywhere from 9-16% of your overall damage on the fight.

(Pre Hotfix)

Kingsbane at 14.49% of overall damage

(Post Hotfix)

Kingsbane at 8.15% of overall damage

Because Kingsbane is no longer double-dipping from Agonizing Poison we can estimate an approximate 45-50% damage decrease. This was obtained by looking at some post-hotfix logs as well as using napkin math.

Using very rough napkin math we can estimate an overall 5-7.5% damage decrease.

Some quick takeaways:

  1. This increases the possibility of Exsanguinate becoming competitive
  2. Alacrity value also increases
  3. Despite an overall 5% damage nerf Assassination Rogues are still one of the best DPS specs in Nighthold.

Note: Estimates were obtained using very unsophisticated napkin math and looking at different logs. Please wait a few days until the theorycrafters are able to sim the changes and provide better data before making any changes to your gearing strategy
