Skada Player Score
This addon is a plugin module for Skada to generate a score based on your ability to perform your role while avoiding incoming damage. It stores your high scores on a per character basis for each boss and difficulty combination that you attempt. It also stores the high scores of the group as a whole as an average. Weightings for damage, healing and mitigation can be customised for each role.
Eg. "/sps Healing 1 2.0 1.5" would set the multipliers for healing done to 1 for DPS classes, 2 for healing classes and 1.5 for tank classes.
Use /sps in game for options.
