For everyone who has ever complained in XI or XIV about tanking on PLD being too hard, unbalanced, and unfair, here's a protip.

Get more enmity.

It was principal in XI, it's the same here. Enmity should be top concern over everything else. Why? Let's go over it slowly.
What does a tank do? > Holds hate so other people don't get their face bashed in.
How does a tank accomplish this? > Making the monster pissed at them most.
What are ways to do it? > Pure raw damage (WAR) or loads of enmity based skills (PLD)

Wait, you mean I shouldn't try to hold hate on my PLD through damage output? WHAT THE SHIT IS THIS SORCERY?!
