Jobs and Classes: Ratios.

[Rydin]

So 2:1 most likely won't happen.
EDIT:
just thought, MAYBE as mentioned above, playing 2 classes together can unlock a 2nd tier of jobs, but the question is, where does the exp go?
(aka GLA CNJ and PGL = RDM?)
This might not sound as crazy as I 1st thought, but who knows...

And here we have 2(+):1

Archer + Musketeer -> RNG?
Gladiator + Conjurer + Thaumaturge -> RDM?

Okay this is where things get alittle strange. If 2 or more jobs are required does that mean we play our job with the options of those classes? Is a system like this going to exist in game? I question this. Will we see things like a RDM freely switching between sword and staff or a RNG freely using bows and guns? (X is not a function of Y here.) I question weather the class system is setting up well if it takes this kind of route, if not then well I guess we will be bound to 1:1(+). And what of the jobs being introduced now, they may only use one class?

In one of the interviews, Yoshi actually gave a hypothetical example of this.
He said in the future, something like Red mage might require both Conj and Thaum

I think it would add depth to the armoury system if a Job was linked to 2 different classes so you could choose between a Conj red mage or a thaum red mage
Or say Thief needing both Gladiator and Archer... Adding a bit of choice to jobs... which would really mesh well with the ideals behind the armoury system
