In XI we had what, 18 jobs? so with the sub-jobs it's 18jobs x 17 possible sub-jobs = 306. It worked out not too bad
How many of those 306 were actually viable? Some main jobs were far from useful as a sub under any circumstance. And many were far from useful under many circumstances. It encouraged experimentation, that's true, and while some experiments succeeded (/SMN for mage comes to mind), many simply were not particularly viable.
