There should be an addition to this: Vengeance was also reduced by 10% at the time that hotfix was noted. We apologize for that being missed in the patch notes. Vengeance now accrues at a rate of 1.8% of damage taken, down from 2.0%.
Based on the hits a tank takes, Vengeance attempts to predict what 50% of average Vengeance for that level of incoming damage will be, and bumps the tank straight to that level. However, it previously based that calculation on a 1.5 second attack speed. It now bases the calculation on the enemy’s auto attack speed for auto attacks, and a 60 second interval for special attacks.
Tanks will still get the expected amount of Vengeance from the damage taken. This change just means that the first hit from a slow-attacking boss will bump Vengeance straight up to the expected amount.
