Adjusting experience gain per action?

[Donkeyton]

Is there any way to adjust (read: lower) the amount of experience gained per successful action? To the best of my knowledge, every successful action carries with it the same exp gain. If I'm doing an appreciable amount of job grinding, my characters quickly become overleveled.

I realize I can: a) use deleveling traps to reduce my characters' levels, and b) adjust each ENTD scripted encounter so that enemies scale up with me. I have already done the latter, and the former I find unnecessarily tedious.

Looking for a solution that would simply slow down the exp gain, i.e., by awarding less experience per action. Not interested in lowering JP, per se.

NOTE: I am referring to WoTL (PSP), not to the PSX version. I know this makes things more difficult.

A tedious work around would be to raise the required amount of JP for job lvls and abilities.
EDIT:  realized u said exp, not JP.

I have an ASM (somewhere) that would help you if you were on the PSX, but not the PSP sadly.  Your best alternatives are to do one of the following:

1. Buy a Level 1 Recruit, go to Mandalia Plains, beat the shit out of him.  As long as your Level is greater than 10 you'll only get 1 EXP per action but the usual amount of Job Points appropriate to your Character Level and Job Level.  If you have an untrained Special or Generic Unit that can wear Heavy Armor and is more than 10 Levels below your party average, they'd also work for being your meatbag.

2. If you consider use of FFTPatcher to modify JP costs as not being cheating (since at this point you're clearly just using it to bypass a time-gate and not make the game actually easier), simply reduce the JP costs of most skills so you can learn them with far less JP.  (Honestly kinda recommended since some classes like Wizard and Dragoon require over 8000 JP to Master.)  This has the uncanny side effect of actually making the game more difficult later on when the enemy has more JP to work with, because they'll come in with better abilities to use on average.

3. Do what you already seem to be doing, get your JP without a form of grind-abuse or FFTPatcher use, then Level Down back to the Level you started at using the same class you trained JP in.  (Using a different class defeats the purpose of Leveling Down to begin with since I assume you want to maintain a low level for the sake of not making the game too easy.)

A tedious work around would be to raise the required amount of JP for job lvls and abilities.

That has nothing to do with what he asked and doesn't reduce the amount of EXP he gains.  Your EXP is not related to your Job Level.  (However the inverse is true, your Job Point gain is related to your Character Level, as well as your Job Level and obviously whether or not you're sporting Gained JP UP / JP Boost.)
