So, while we're waiting for the new jobs to appear, let's say try to imagine what kind of new jobs that could come from the current classes.
First a few rules.
1: The job has to be a classic Final Fantasy class. At least it has to be featured in a previous Final Fantasy.
2: It has to come from a class.
3: Try to specify a specific role in a party that it could fill. Try to be unique.
Now, on to the imagining.
