I game across this : " Yoshida is also still considering removing the class/job restrictions on existing dungeons to allow people to go in solo, or perhaps with a team of NPCs. The NPC system being considered, for example, is to be able to take members of your Grand Company and raise a team or squad that could fight with you. Unfortunately, this new system would not, however, include your Chocobo Companion. They are considering a gambit-system for the Chocobo Companion (and Magitek). This system is pretty definite, but includes a few aspects, and is perhaps a year or so away from release."


I have to say I would love to raise my own Grand Company squad and can't wait for this to be implemented.
