Puppetmaster Job indirectly spoilered due to Rogue Storyline?

[Xandim]

All SE needs to do add in PUP as is it now in XI, which will give you 1 customizable pet where you can switch it roll based on how you customize it - Though that seems too complex for ARR, sadly. The only reason people say XIV has better balance than XI is because they made everything so homogenized nothing is really...different.

I prefer this way, so we can actually play whatever job we want.

On topic tho, don't get your hopes up too much. It might be a hint or it might be just fan service. ROG/NIN was "introduced" in the main story, and this is a class related quest. Besides, when saying what jobs Yoshi would like to see, he always mentioned jobs like SAM, DRK, even RDM and he always felt that a "scout" class was lacking in this game.
