Luanne's character development was wrecked by the writers never having a clue what to do with her character at any point in the series aside from the Buckley arc.

She started off as a competent mechanic before that aspect of her character was dropped and never referenced again.
Then she became the struggling beauty school student with a ditzy side.
Then she got the Buckley arc and had some phenomenal character development, leading to her going to college.
Then the writers did nothing with that for years before having her unceremoniously drop out and go back to hair, and having her become a stylist in a matter of minutes while ignoring that she always struggled in beauty school.
Then she just became a flat-out moron in later seasons before being shoved into the Lucky thing just to give her character something to do.

Her character was a mess aside from the Buckley stuff.
