Do you usually change the traits of the premade sims if there is one you cannot handle?

I mostly play my own sims but there are a few premades that I love using for their genetics although I do change them a little because they usually have too many zero slider settings for my taste. Because I play for genetics and don't want drama in my families, I will give sims whatever traits I need to keep the peace.

As for kids presiding over royal court, I have had many who didn't have either the excitable or insane traits who would do it non-stop. I use Nraas Retuner to get rid of many autonomous behaviours that I found annoying.
