A Skada plugin mode for tanks to benchmark their damage reduction performance via avoidance and mitigation.

Requires the Skada Damage Meter.
Now Fully compatible with Wow 6.x!

What the numbers mean:

The top-level module display shows total avoidance and mitigation - the fraction of attacks against each player that were either avoided (eg dodged, parried) or actively mitigated (blocked or absorbed). Mousing over any player shows a tooltip detailing their most common forms of avoidance and mitigation. The tooltip also includes with the average amount of damage blocked/absorbed for each attack which is mitigated, and the average mitigation reduction for each such attack (eg. blocks usually mitigate about 30%, full absorbs mitigate 100%, partial absorbs mitigate less). The total lines show the total amount absorbed or blocked, as a value and a percentage of the total unavoided damage.

Clicking on any player shows a full breakdown of the number of attacks made against that player, categorized by how they were avoided or mitigated:

Dodge, Parry, Miss, Reflect, Immune: Attacks that missed entirely due to the stated avoidance mechanic
Block: Attacks that were mitigated by a shield block, which generally reduces damage taken by about 30%
Full absorb: Attacks that were completely absorbed and thereby fully mitigated for zero damage taken
Absorb: Attacks that were mitigated via partial absorption - ie damage done exceeded current absorption value, resulting in some damage taken
Physical Hit: Melee swings and physical school attacks that were not avoided or mitigated in any way and inflicted full damage.
Spell Hit: Non-physical attacks that were not avoided or mitigated in any way and inflicted full damage.
Crit, Crush: Attacks that inflicted a critical hit or crushing blow on the target. These should be very rare in PvE for correctly-speced tanks.

Misc Notes:

Due to combat log limitations, absorb mitigation includes absorbs from all sources, not just self-applied absorbs. So for example with a discipline priest in the raid, players will tend to have inflated absorb mitigation.
Currently only direct damage attacks are recorded - DoTs are ignored, as they generally cannot be avoided or blocked and would skew the display.
Mitigation via armor, damage reduction talents or damage reduction cooldowns is not shown, as this information does not appear in the combat log.
Mitigation via spell resistance is not shown, as spell resistance has effectively been removed from player tanks starting in 5.x.
