Yoshi - Are there any plans to make the cross class system better/more fun?

[Naunet]

I would say that they designed to be useful; they are designed to lock players out of being two jobs at once.

Except they don't actually do that at all.

I like to think the class system in this way, each Base Class is the same as a Class in other MMORPG, and each Job is like a talent tree of the Class. So when we have more Jobs coming out, the system will make more sense.
So people will have variation to their Base Class(using different Job), and not so much variation when using the same Job(choosing the same talent tree).

It's close, but not quite like that, because talent tree variants in other MMOs would have completely different skill sets, whereas the current Class-->Job system means Jobs are only distinguished by five abilities. It's a stupidly limiting system, to be honest.
