I don't understand why PLD needs to have access to both Passage of Arms and Divine Veil. You can easily limit each tank to just one unique defensive raidwide mitigation tool in a way that is fair and balanced. And if worst comes to worst, just get rid of all of them and give tanks the Troubadour/Tactician/Shield Samba treatment. Why is there so much mitigation bloat?

I also don't understand the naming choice for Dark Missionary. What does that even mean? Is it a religious order? Is it a position? It just sounds like they completely ran out of ideas after giving all the good stuff to PLD and WAR.
