Job and Subjob system instead of classes?

[Engineer]

Pug= Monk no one else can be a monk but pug they said this before it lock by Class. They said later they going to add more Jobs for each Class and also be something like THM/CONJ= Red mage so you need both the class at a level range to become Red mage they said they thinking of this they may or may not do this part but the class lock per job yes they are.

Im not saying thats what they are going to do, im saying the idea would be more realistically doable than the proposed OP suggestion and would be similar to a job/sub job system.

Also let's face the fact that SE said that multiple classes will unlock certain jobs in the future IE. Thm+Con = RDM. If thats the case, then red mage can't be locked to one class because Thm and Con unlocks it. This is a huge hint that jobs won't be locked.
