I could see taking a class is if it allows me to carry in every other state in the U.S.A.
If it means reciprocity in more states, which it definitely would, then yes, I'd attend a class. I wouldn't learn anything but if it makes other states feel more cozy and let me CC in their states then I'd swallow that pill.
The question wasn't what perk it would take to get you to merely attend an offered class, it was what would you trade for it to become a mandatory prerequisite to licensing.
