The question is, why aren't these PLD using Flash?

Flash 2 times at initial pull = Confirm agro for at least 2 Halone's combos.
Flash after every other combo (after every 2 Halone's combos) = Confirm agro for the rest of the fight.

Ran out of MP? Replace Halone combo with Riot Blade and you're fine.

Again and again. I have to say those things in Haukke and Brayflox. What makes tanking as a PLD before you have Sword Oath any different than tanking as a PLD after you have it or Shield Oath?

Pro-tip: Nothing.
