You mean those traits? They can be changed, and will be, rest assured. I have some fine ideas on a complete new system. In particular the nonsense that every general gets the same traits when doing the same things is not acceptable. Some guys would just be noble and chivalresque, others would rather be the "bad guys".
And of course, no one would become an alcoholic because a brothel was just finished in the town he accidently passed by; or a living saint when he happened to be in the city the day the bishop finally finished his new cathedral.
