So you're telling me..

Damage buffs come with the biggest penalty to damage. That's how it's always worked in this game. The more damage support you provide, the weaker your personal damage will be.

sorry I was assuming we're using rDPS for this tier thing
at least in my opinion after the damage buffs have been taken into account buffing the raid, DRG and NIN should come out on top by a few 2 digit numbers or so ahead of monk and RPR who have mantra and AC and then SAM #1
