I really like the export system, but it does read a little cluttered. I think it could use with the removal of a few columns.
Damage Taken, for example, seems a little irrelevant in pve because hypothetically the tank should be tanking all the damage
Damage Taken is good in pvp exports because it helps players acknowledge whether they're taking too much damage due to poor positioning. In pve, this is a non factor. If you're taking damage, its like an aggro control issue, which can be measured by deaths vs Damage Taken.
As for Damage Absorbed, I'm not really sure what this is measuring. I'd consider the removal of those two to make the export easier to read. At least Damage Taken.
