I googled a lot for this question but it's hard to get a final answer to this question because the PSP system seems to be very different from the original one, since on PSP class levelling is global.
As far as I understand, in the PSP version, the answer to my question is 'NO', since the only stat's increment is about base stats (+.1 to all base stats when levelling up.). So there is no difference in gaining 10 levels in the Warrior class and then switch to a level 1 Knight (for example) than gaining 10 levels in the Cleric class and then switch to a lavel 1 Knight.
Am I right?
