If they had any sense they'd take all the classes and stick them on one Job which works similar to 1.0s original physical/skill leveling system. Everyone starts out as a Freelance, your weapon decides Freelancers skill set (sword = Gladiator skills, for example), level the weapon skills on Freelancer to unlock Jobs, the more Jobs you have unlocked, the more powerful Freelancer becomes, just like old school Final Fantasy style beginner Jobs. Freelancer (Arcanist) becomes just as viable as Summoner, and people even get to keep using Carbuncle if they want.

Been suggesting this since beta, just do it already Yoshida...
