I think people are missing the point here getting caught up on the cure pld example.

Let me give another example. In v1.0 the abilities you could cross class were so much more varied it's ridiculous. You want to play as a DRK? They don't need to add the job, just play as a MRD and cross class THM spells and LNC abilities. You could actually use Fire, Aero etc. As a melee class.

That's how the armoury system was advertised. You levelled up classes to unlock abilities you can then use on other classes.

Now it's just pointless. We have effectively zero class customisation. Not even a trait tree or anything which is usually the bare minimum in an MMORPG. And it's a shame.
