Let's Find Those Trait Improvements

After reading several comments on here, I think the problem isn't people wanting Sims to still act the same as before, but more of that they want there to be a balance between Sims doing what one of their traits makes them do and other interactions. Like, Goofball Sims should definitely do Mischief interactions and Funny interactions, but there are still two other traits (if the Sim is an adult) that should also be given attention and more types of interactions for Sims to do. A Sim should do a mixture of everything, with a little more attention given to the three or less traits they have so that they don't just do one thing the whole time. I personally like it when my Sims do something that is not related to their traits, such as a more friendly Sim getting angry and then being rude to everyone else. I find that fun! However, I don't know if it would be possible to achieve this balance to make everyone happy. Maybe in the future? Who knows?
