That doesn't matter. Consider this:

DKN: Deals 300 DPS, durable, can tank
DRG: Deals 300 DPS, squishy, can't tank

Who will you take? The mere reliability of DKN DPS alone makes it superior, and the ability to tank at will means you have yet another disincentive to bringing a dedicated DPS. But Gamemako, what if DRG has slightly higher DPS, I hear you say. MNK and DRG would already out-DPS BRD in 2.0, but they were still summarily ignored in favor of 2 BRD groups and essentially brought only for the LB. If a tank could do more damage than it already does, it would start taking over DPS slots because a tank is almost fool-proof. WAR can passively eat WW, DRG can't. PLD can tank any add, BLM can't.

Put simply, WAR and PLD are as close to a DPS as the design can allow. Going higher requires that they lose the ability to be MT.
