This isn't that they don't understand, considering that the job is what they want it to be, it's that there's a conflict in what players want and what squenix wants. I'm under the impression that squenix specifically didn't want offensive aetherflow dumps on sch, and it's possible that they don't think aetherflow should be used on cooldown, this obviously conflicts with what players think, but they made the job, and they are allowed to do what they please with it.

That said, I wish they'd convey what their intentions are.
