When comparing in tank stance damage, this is true. WAR can do more damage in Defiance than a PLD can do in Shield Oath. WAR just has more offensive damage buffs, and paired with Unchained, they can unleash at pretty high power for a while.
When comparing in non tank stance, though, PLD can do the better damage in Sword Oath than a WAR can without Defiance, especially if the MT is a WAR who is keeping up the Storm's Eye debuff. The extra auto attack, even at a reduce potency, really starts to add up when you're throwing in Fight or Flight (and Strength potions if you really feel like it), and with the added debuff damage.
