In this case I'd say it was a matter of them not cooperating with us. Whether it's because they believe we might not be Heroes of Light or for some other reason, I couldn't say.

As of yet I haven't been able to switch between jobs though I've tried. It's something I was able to do back in my world so it can't be a lack of experience. If these crystals are supposed to be connected to us, I would rather have it with me than in someone else's hands.
