The bright side from this update is that it should make PLD better than GLA for more situations now, whereas GLA used to be superior to PLD in almost all situations.

A WAR can still be cut down without proper healing attention, and a PLD can maintain themselves better than a WAR can. I respect the WAR ability to heal themselves with Crits, but PLD has much more with Holy Succor and Aegis Boon. A properly timed Aegis Boon can intercept a physical TP attack, heal you nearly to full, and allow you to Phalanx > Bloodbath > Spirit's Within to recover the rest. Plus the PLD healing spell is very potent, able to crit on for over 1,100.

Ultimately, I have to agree with what Lux has said. They are two different types of tanks that excel at different types of tanking. PLD makes it easier on single target NMs by sustaining itself and requiring only one healer in some situations, while a WAR will tank and tear through lesser enemies without much need for any support either.

If you reverse those roles, WAR ends up needing more healing on a single target and PLD ends up needing a little help killing off lesser enemies.
