We are changing how Critical Strike, Vulnerable, and Overpower damage is calculated. These damage types will now always have a baseline multiplicative bonus. Additional sources of bonus Critical Strike Damage, Vulnerable Damage, or Overpower Damage will be additive to your other damage bonuses.
This change represents an overall decrease in damage output, so we are adjusting monster scaling to ensure that the best Class builds are still as powerful as before. This change is not intended to lower the power of the best builds, but rather allow more builds to reach that same level of power. We have also added a variety of mechanics to classes that encourage them to chase other stats for multiplicative bonuses, rather than always chasing Critical Strike and Vulnerable Damage.
