They need to quit declaring a job "balanced" as long as it's somewhat effective at something/anything. "This job is good at farming Dynamis! What more to life is there?" If they want to do other stuff they can just level another job!" That seems to be their philosophy. Ideally they would treat each job as if each character could have only one job at 99. That's not to say that every job should be able to fulfill every sort of role, but each job should have something beneficial to offer within its general archetype. It shouldn't be so easy to decide which DD to take for example, or rather it shouldn't really matter. They should all get you to the same result even if they take a different path to get there (aka play differently). The devs and many players don't seem to want to wrap their heads around that concept of many paths, same result.
