I've heard vague comments to the effect that the writing staff of Frasier got shaken up considerably during the last few seasons. Specifically, I heard that many of the writers of seasons 1-7 left, and then came back for season 11. Is this accurate? If so, is there any information about how the season 8-10 writers planned to resolve the season 10 cliffhanger, with Roz leaving KACL?
This probably means that the producers wanted a creative sea-change to get the show back on track. The original trajectory for season 11 is unclear, but here's a half hour interview with writer Christopher Lloyd.
