I don't want to invalidate class growths, and I understand that setting up your growths can be bothersome if you're going for something a bit stranger. I think I'd rather tackle that issue some other way though; for example, a Legend Extend category that overrides your class's growths with another class' (could even add a toggle to the character info screen to turn it on/off, and have one for subclasses too). That, for example, would make it a lot easier to extend, set up the class growths you want by buying the relevant abilities, and then just level with the classes you want to use.

Other random ideas of debatable relevance/goodness/badness.

1. Fruit items that decrease one stat by 1/some number and increase another by 1/some number, up to a cap.
   
2. Legend Extend category that swaps two growths (STRWIL, for example) of your main class.
   
3. If you really want to minmax and make everyone boring, a stat point distribution system would be better. Or the old test of the 'fixed growth system'.
   
4. Elona had it right all along.
