I think her leaving saved the show and reinvigorated it because when Kirstie Alley came in, she brought a different dynamic. The first season with Alley did try to recreate the 2 leads dynamic so a lot of it has Sam chasing after Rebecca but then they realized Sam and Diane could never be recreated, so they turned CHEERS into an ensemble, everybody got their due, and that made the show even more popular than it already was.
Shelley Long made the right decision, she had a fairly successful career in movies though not as big as she might have expected. And by Season 5, Diane had pretty much turned one note. How many times is she gonna threaten to leave or dump Sam to then have him back?

Her leaving Cheers was the best thing ever for Cheers. They got a reboot. In my opinion; Cheers was two different shows : (1) 5 yrs of will they or won't they with Sam & Diane & (2) six years of more of an ensemble show.
