Description

The numbers reported for Enemy Damage Taken from particular players differs from the numbers reported for the damage those players have done to the unit. I noticed this bug on Heroic Maloriak in particular, with the damage on the Vile Swill.

Reproduction Steps

This is reproducible on any fight, though its easiest to notice on fights with 20k+ damage on 2 or more enemy targets. Engage the enemies, and look at the "Damage" mode mouse over the people who did damage, and note the amount of damage a player did to a specific unit. Then back out to the "Enemy Damage Taken" mode and note the amount of damage done by that unit. These numbers will differ significantly (20%+).

Could this be down to mitigation/absorb abilities like shields. Say for example on Council, burning down the shield might count as Damage Done, but as the boss doesn't actually take damage it wouldn't count as Damage Taken.
