Bonus stats are pointless

[L-D-Omlette]

Why would you even need to choose? SCH already gets a different stat loadout from its levels compared to SMN (and, in fact, gets a boost to MND to compensate for the INT traits) so there wouldn't be any trade off between the two: SMN and ACN would simply have 30 higher baseline INT at 50 and SCH would simply have 30 higher MND. The only thing that you inherit when you go to another job is the class abilities and the bonus attribute points; the actual base attribute points are determined solely by the job itself.

I must have misunderstood your original statement then. This makes much more sense.
