If you're looking to gain more accuracy, I'll suggest going back to using Darklight Choker and Bracelets of Fending. Both of them gives you a +21 over your current Accuracy, at the cost of 8 VIT/roughly 112 HP. While VIT is an important tank stat, but 112 HP isn't enough to break the game by any means either.

For your PLD, you might want to go back to Heavy Darklight Gauntlets, as that is a +16 Accuracy. And as mentioned before, Heavy Darklight Flanchards give you +43 Accuracy, which is not anything you will be beating anytime soon. For your WAR, have you considered getting the Dual Haken instead?

I'd suggest sticking in gear that gets you as close to the Accuracy cap as possible, instead of choosing to maximize Vit and Parry now. You can maximize those stats later when your Accuracy is close to your target accuracy (if you're not attempting T5 anytime soon, you'll want 477 Accuracy for up to T4).
