Is kinda obvious. Duh we don't use PLD to tank, because you cant tank right now, tanking is broken by AoEs and enmity, tanks cant hold hate in a way that allows them to hold the mobs attention away from the army of people beating it with sticks. If it were fixed, a hypothetical situation we are hoping to see in the future, we would also need AoE spam to be eliminated. Am I saying get rid of all of the AoEs? No, I am saying make it so that not every attack is an AoE, which is how it is right now, everything is conal or AoE with varying ranges some of which reach even max casting range. These types of things would have to be stopped. If you stop those 2 problems,
PLD becomes unstoppable.
