The thing is PLD is supposed to have low damage output but alot more survivability and more hate tools than raw damage (cures and shield for example), WAR is supposed to have DD amounts of damage output, but less survivability and less hate tools (provoke and raw damage).

This makes both jobs situational do you need to sacrifice raw damage for survivability and hate control, or is it vital you have high dps? For the formor use a PLD, for the latter use a WAR.

The problem is SE's fixation with speed runs right now, making dps important which is a big reason why WAR is perfered over PLD.
