Nope!

WAR Myth set is actually exactly the same as PLD's.

Valor Head: 21 / Warrior Head: 0
Valor Body: 0 / Warrior Body: 24
Valor Hands: 0 / Warrior Hands: 21
Valor Pants: 24 / Warrior Pants: 0
Valor Boots: 21 / Warrior Boots: 21

So PLD pulls ahead by having accuracy on Curtana and Holy Shield. There's ways to make up for this through crafted gear and Allagan gear (obv) but it's a struggle to maximize anything if you're planning around pure Myth purchases and hoping for Allagan drops. It's way easier to gear up PLD and you'll rarely run into problems with accuracy with anything you buy unless it's all pieces where you lose accuracy.

Allagan Axe gives us ACC, so hopefully the EX Primal Axe also gives us some ACC...
