This is total nonsense, DRG wont generate enough enmity to over take tank (even with potency buff) in the beginning due to time required to build burst dps. Low (or huge gap) tank ilvl gear might be the only reason that DRG is able to rip off aggro from tank.
Given the same up time and same Ilvl between DRG and MNK (Nvr raided with NIN before). We are around 40-50 dps below them. A good MNK will always be able to generate this DPS gap.
