Wanted to reply to one thing you said in particular: you're giving Divine Veil way too much credit. You know that it has zero effect on the PLD himself/herself right? Of the 4 tanks, PLD is the only one whose raidwide cd doesn't help them as well. That's pretty bad, and the ~4% passive mitigation from block does not make up for this honestly.

We dl also have PoA, and once again, it doesn't really give any meaningful effect to the PLD using it since all it does is guarantee a block for us, but we already have sheltron to do that for us; on top of that, if we were going to block the attack anyway, PoA would have literally had no effect on us.

Honestly, my only suggestion for PLD going forward, would be to stop making us so dependant on block for our mitigation and add other types of defensive buffs for us. Or, make block much more meaningful.
On a side note, it just makes absolutely no sense to me why SE would buff the heck out of TBN's defenses (a defensive CD that's MEANT to break) but butcher PLD's defenses (the class that's always been known as the Bulwark amongst the others).
