Assuming PLD can even dance like a WAR, PLD is only ~8% DPS behind WAR. PLD isn't the only clunky stance dancer and DRK pays more MP with Grit alone than PLD going to Sword Oath and back to Shield Oath. Usually by the time you want to go back to Shield Oath, it's almost full. MP is not even a vital resource for PLD and is very easy to refill. I won't argue why PLD stances should remain the same way and not be similar to WAR's stances.
So, it is fair to calculate the bonus lost from Sword Oath and add it to the malus from Shield Oath, but not the bonus from Deliverance and loss of 200 potency per Inner Beast that WAR loses? Your logic is astounding.
You want to throw some percentages and potencies at random? I can do that too! So let's do it!
DoTs You have the second highest potency skill in the game: Goring Blade at 540. That's higher than *gasp* Fell Cleave! Fracture is shit in comparison at 300 potency and 80 TP and no wrath/abandon generated.
Combo Finishers You have Royal Authority at 340. That's 60 potency higher than Delirium (DRK's strongest non-DA finisher). That's also 80~120 potency higher than any of the WAR combo finishers. It is actually so strong that the only DPS with a stronger finisher is DRG!
Off GCDs You have 2 VERY potent oGCDs on short CDs in SW (300) and CoS (250).
WAR has Maim for a reason: It has generally lower average potency on all its combos than PLD and DRK and WAR has no oGCDs.
More to the point:
PLD is no effing where near AST. AST is pure garbage. AST is almost as bad as 2.0 WAR.
PLD is no where near pre-2.45 DRG. DRG wasn't as garbage as you make it sound. Content has been cleared with DRG at a relevant time. People didn't need to "outgear" T13 to beat it with a DRG. The problem back then was MNK's INT Down was too strong to ignore. DRG was second highest single target DPS and did at least twice or triple the DPS of a monk in AoE. DRG was fine in SCoB and DRG only got into a bad spot when NIN came out. NIN did higher DPS than DRG and increased raid DPS with TA and Goad so it pushed DRG out of raid comps. DRG was never in a state similar to AST today. Actually for the entirety of 2.0 and most of 2.1, DRG had a VERY solid raid spot when DRG/BRD/BRD/BLM was a thing. Bringing DPS balance when it's been dancing so much with far more (7) classes to fill twice as many spots as tanks is totally irrelevant.
Bringing up DPS imbalance is irrelevant since tanks are FAR MORE BALANCED than DPS. Also get it through your thick skull that Lucrezia dropped a DPS class for another as well.
Again, you are not Lucrezia or even anywhere near world 200th. You play on a whole different level. I'll quote myself:
Let's not forget that Lucrezia tried with a PLD MT first before they finally decided to go DRK. And the main reason for DRK over PLD is INT Down since they dropped the monk. Yes, PLD is THAT good.
Ultimately it feels weird that you have such a kneejerk reaction to PLD having slightly lower DPS than WAR when its main role isn't even to DPS.
Again, I'll quote myself:
No body is saying tank DPS is irrelevant. Difference between the tank classes DPS however, is irrelevant!
Honestly I can't take you seriously if you argue these points any more.
