Everyone is talking about Damage output.

The big elephant in the room is PLD hate is very low compared to the other two.

Leveling a PLD is literally a struggle of flash spam and rotating enemies as you desperately try to build enough hate to keep them on you.

I like PLD, but the fact that its lower dps as MT and OT coupled with its threat issues is a deal breaker. Mitigating damage is only a piece of the pie.
