The following statement by Rustyhagun is false:

They are scrapping the system we are playing with now, you don't believe me? Then we will see.

Two Q/A both from different fansite interviews.
Q. You have also mentioned the possible introduction of traditional names. How do you see these new names fitting into the existing class system? Do you plan on using the new names as a guide to develop class uniqueness?

A. Yoshida-san is between two possible plans at this time. The first idea is that the traditional names would be introduced as “higher” or “advanced” classes. The traditional classes would thus be something of a goal for players. The second idea is that the traditional names would be more of a subset or specialization within the existing classes.

Whatever change is put into effect needs to be right. He recognizes that he will not be able to change the system again after this, so whatever is put into place needs to work, and be able to be balanced, for years to come. Because of this his team is giving this issue a lot of thought prior to implementation.

Q:If you take out the physical level system, do you plan on adding ability trees, sphere grid, licence grid, etc type systems (Final Fantasy spin on classic MMO character building) that will still allow us to build out our classes as we please? If so, what are your thoughts, if not, what are your thoughts on the whole physical leveling system in FFXIV?

A:We're not looking to copy what other MMOs are doing. But we are looking to move in that direction, and right now the battle team has two options that they're thinking of. And basically, they're battling against which one they're going to choose. We're going to be moving in a similar direction, but it's not something that copies another game.

And with that, we want to get back to the roots of the original Final Fantasyesque jobs like Dragoons and White Mages. So we're trying to figure out how to get that to that new type of system.
It seems that the development team is leaning towards a system that incorporates concepts from other games as well as Cairdeas' proposals. This is reassuring in my point of view, as it is a very healthy implementation of "don't fix it if it ain't broken." Many players from many viewpoints tend to cite this philosophy in their criticisms of the game.
