Re: TheGodBen Revisits Deep Space Nine
According the MA (with the Companion as its source), they were originally planning to do a story about the Changelings on Earth as the season finale, and their meddling in internal affairs would bring the Federation to the point of civil war, with Vulcan officially withdrawing. The cliffhanger was going to be Starfleet opening fire on a Vulcan ship in Earth orbit, or something like that. Paramount instructed them not to end on a cliffhanger so that they could pull some sort of ratings stunt for the season 4 opener (which eventually became Worf and the Klingons), and their original idea was pushed back to mid-season with some modifications.
That would have been 10,000x better than Worf and the Klingons. CURSE YOU, PARAMOUNT.
