By your logic, adding Jobs at all was redundant. They share almost all of the abilities of their base class[1]. SE had to add extra abilities and a stat boost to differentiate them.

Thus I don't see how extending Classes into full Jobs by adding extra abilities that other Jobs won't get and a stat boost is any different.

It will be like, you play an ACN to 30, at which point you can,
  • continue with ACN as a Job and get your own unique set of abilities and the stat boost or
  • you can pick SMN or SCH with their own unique abilities and the stat boosts.
