The only time that would happen is if the tank's ilvl well under said DPS, in which case the argument is moot anyway. If you compare an equal lvl/ilvl tank and DPS, the tank simply has to be in tank stance and spamming their enmity combo to hold aggro, regardless of the DPS's buffs and output, they simply will not peel aggro off after enmity is established.
Look at the numbers for DRK for example: with Grit 2.7 multiplier, hard slash has 405 potency, Spinning Slash has 770, and
Power Slash 1650 potency (1950 with DA). At minimum that is 2,825 potency in 9 seconds. There isn't a DPS that will do a more potent consistent combo than that of a tank in defensive stance. And that's simply if the DRK is only doing their basic enmity rotation.
Tanks tend to lose aggro when they deviate from that rotation to either buff or maximize their DPS.
