Please also remember this from Matsui-san's battle reform blueprint:

Classes
Actions will undergo major revisions, along with both the underlying mechanics and conditions.

By major revisions, not only do we mean the tweaking of effects and potency of existing actions - we will work from the ground up to redesign and reassign actions based on clearly identified class roles.
The class roles are being reworked, actions are going to be re-assigned to different classes (in some cases). So, the interaction between class and job is going to be hard to imagine, since we don't have a clear picture of what the classes themselves are going to be.
