So this game has dps checks but we can't talk about our dps in game?

*Laughs in 2nd place dps shown in ACT latest 8man raid as SAM but listed as 4th place aggro".

Yes, aggro list "very accurate" in showing who doesn't know how to play their job.

It's not that difficult to discount the tanks and shift everyone along two places.
Aggro has a direct relationship to damage dealt, so you can absolutely just the dps output of the four dps jobs by aggro alone.
It's only the tanks, and sometimes the healers, who are outliers.
