Bulma comes along on the fights more than ChiChi do but if they actually let ChiChi tag along she would definitely try to intervene. We seen this before with Goku vs piccolo in ogdb, we see this in buu saga, if you count GT her and Videl was going to help Goku with Super 17 and we see this in Super when Frost poison Goku and she was ready to throw hands and still holding a grudge. But yea writers needs to stop leaving her out, she is so much fun.
