I do not main nor had brought any tanks into High End contents across my 2 years of gameplay. But I do want to say that amongst 4 tanks, I've used to enjoy PLD's rotation in ShB and only grew to like it more in EW, especially with added flexibility of Divine Veil usage within magical phase. Requiecast cooldown, Fight or Flight cooldown, Explacion cooldown, Circle of Scorn cooldown, Goring Blade DoT, and Blade of Valor DoT all makes a good personal 'timer' and my reminder of what rotation I am currently in and what should I be expecting next. It feels fluid and awesome to execute properly.

(That being said, I still enjoy being a WAR more than PLD but that's not because of their rotation. An aesthetic reason, rather.)
