In my game you can choose between 3 Classes and there is one that is like that, I can't guarantee that it will be to your liking, but there it is...
The strongest content can be ignored and it will not affect your progress...
PD: as I see that it fits quite well with what you are looking for (a lengthy rpg) I invite you to try the demo, and if you really like the game I can give you a key, just write me to 4.melinda.lovers@gmail.com
