Job and Subjob system instead of classes?

[Corrderio]

No class is unique, no class brings anything to a party (recent healing changes somewhat changes this, but all frontline are still exactly the same with a different weapon graphic.)

Nothing works well in FFXIV, which is why they're introducing the job system. They wouldn't be adding the job system if they decided the class system is absolutely perfect.

And? Nothing stopping SE from doing what you said with the classes.
