As a former tank main I think both sides of the equation are broken. Ran through ARR as a Warrior and never stopped to think "if only I had Hallowed Ground on a 25 second cooldown I could clear this pull" and switched to DRK once I hit Heavensward which is... certainly one of the tanks in the game.
Last time I played it was a Praetorium run where the Sage spammed Prognosis, not E. Prognosis, Prognosis. I'm sure Duty Finder will be in good hands while I play PIC.
