I understand your point and it is a valid one. I am saying that defensive settings is an option that you can turn on or leave on auto. If the pnr settings are on auto I agree with you 100 percent. But, if I give them an assignment like switch everything then I want them to switch everything and stick to the "script." Unpredictability (if that's a word) is the opposite of what I want when i set my defensive settings.
