It seems that in the entirety of this thread, not a single person has tried to parse any data on a dummy or use optimized rotation that an off-tank would use during burn phases such as the first Dreadnought in Turn 4. (As in with Defiance off or Sword's Oath on). Since I got into an argument with someone claiming that he did 171 dps on a dummy with WAR and 170 with a PLD over 3~5 minutes test time without any evidence to back it up, I've decided to do some tests myself with the PLD tank in my static Coil group and thought I'd share the result.

These tests are conducted on the level 1 dummies right outside the Gate of Sultana in Ul'dah, both of us wore full Heavy Darklight set with Vit accessories using Relic+1 and attacked until we ran out of TP. PLD didn't stop using DoT at the end which cause the DPS to drop after he stop attacking the dummies, however, I did write down the DPS the instant he stops attacking so please refer to those instead of the DPS number shown in his tests.

Also, do note that there's the fact that I put 20 points into strength and 10 into vitality instead of the full 30 points into vit on the Paladin. According to Valk's formula, that would account for a 4.89% increase in DPS on my end.

Warrior:
188.38 DPS (179.16 after deducting 4.89%)
191.30 DPS (181.84)
185.32 DPS (176.25)

Paladin:
136.67 DPS (without Storm's Eye debuff on the dummy)
157.32 DPS (with Storm's Eye debuff on the dummy)

There seem a much larger discrepancy than people suggested and I couldn't see anything wrong with the rotation that the Paladin was using either. If any other Paladin would like to post more result using the same condition please help provide data if you can.
