I disagree with the notion that the best way to learn a job is to book it to 60, get all your abilities, and THEN learn the job. The addition of DRK made it painfully, PAINFULLY clear that dropping a newbie into a dungeon with no notion of what it took to build up to those abilities is a recipe for disaster - even just at level 30! Doing the same for level 60 would be so much worse. Before a tank can tank, they need to know how enmity works. Before a BLM can master Enochian, they need to understand how to maintain Astral Fire.

Also, as for the whole "unfun" aspect, you have no one but yourself to blame if you reached level 60 through three days of endless FATE grinding. Forget about FATEs. Not only are they boring, but they don't teach you your job at all. Stick to daily Roulettes. Sure, you won't get your job to 60 in half a week like you could with FATEs - but why do you need your job capped that quickly? It takes less than a year to cap every class by way of Daily Roulettes, and most of us will be playing this game far, far longer than a single year.
