Sorry if this is a little verbose.
OK, my present character Jules has been a fun character to play to date. She leveled up in curves as I planned meaning; when I need her to get to a certain level in something she levels quicker, and then slows down leveling when she meets certain goals by no longer needing or using certain talents or skills switching to others that changes with her growth as her story unfolds. Everything was working great and I had no idea where things would end up.
This is where my problem comes in; the last two characters started out great then after completing the main quest they slowly move into the 'goody two shoes' behavior and wrongful doings no longer fit the character. Running around saving the world as a great hero gets boring fast. I have come up with a ton of excuses and plots to break free from this mold and none match the character's developed personality.
Which means starting another charactor (I'm going to use the same recipe as I did with Jules) without completing the MQ.
My thoughts are the main quest by its nature is responsible for narrowing the RP growth options.
I would appreciate your thoughts and experience regarding this.
