I think you mean new Jobs, OP. Classes are the base class, the thing you are when you don't have a soul crystal equipped.

Nit picking aside, I'm hoping a Puppetmaster in the same vein as the Puppetmaster from XI is given to the Pugilist (Puppetmasters in XI fought with hand-to-hand weapons, Mammets are the Automatons of XIV, and they're made by a join effort between the Alchemist and Goldsmithing Guild, which are both in Ul'dah along with the Pugilist guild). If anything comes out of the Conjurer, it should be the Geomancer, which just makes all kinds of sense. Since we know Musketeer is coming, I'm hoping with every onze in my body that the Corsair comes from it (Corsairs being pirates in XI, and Limsa Lominsa is THE pirate city of XIV).

And well... *coughPerformercough*... Because Thief is an iconic, classic Final Fantasy job, and those you get when you equip that soul crystal. It should never be what you tend to forget exists once you hit level 30. If anything, Thief and Ninja should be unique jobs that branch from the same base class.
