The Armoury system was created for fanboi's (imo). We fanbois know what skills a WHM has, A BLM has, a RDM has, a MNK has, a PLD has, ect, and what roles they play. What squeeeeeenix did was give us the tools, albeit not all the tools...yet, to make these archetype "jobs" by ourselves.

So SE should reiterate the fact that we don't have set "jobs" and post some builds to fit certain roles for those who need their hands held.
