I'm a developer too and I'm no stranger to the face-saving "working as intended" line.

The job system "encourages" quick switching between different classes / jobs. If the game is so angled toward playing one character with multiple jobs, why arbitrarily force segregation between two of them?

It's not like it makes practical sense. If I can go from DRG to BRD to BLM and back in 10s, I should be able to do the same for SMN / SCH if I so wanted.

To those using the "well it's one class for 2 Jobs" argument, sure. I would even prefer they got rid of the split and made you level another 50 SCH or SMN independently. At least then you'd be able to work up to having instant (and optimal) switch between what could be two of your favorite jobs.

That's the point. This smells strongly of oversight. If this was game design "working as intended" truly, they wouldn't have shoved ACN on this boat all on its own, but rather presented each class with their own "dilemma."
