The idea is to make it more like the FF tactics series, in which you level several classes which then combine to become jobs, level jobs to combine to become specialized jobs.

So yes, this type of level progression is a LONg term progression.

For example : Lets say you want to become a SAmurai (yet to be released ) And to be a Samurai will be like maybe Paladin level 50 and Dragoon Level 20

Well to get Paladin you have to Level two other calsses, and to get Dragoon you have to level two other classes....I can't remember which....

It's a more Dynamic system and alot of fun!
