One of the statements Esther Shapiro made was that they "run out of stories for the older characters at some point," although season 9 showed that even that was not true--Alexis and Blake sure had plenty to do there. But after the first season which many find on the slow side, the other seasons just burned through storylines without having characters reflect on them in a meaningful way like they did in season one and frankly often tossing aside storylines or concluding them too quickly. The very same thing that most of us praise the most as catapulting Dynasty to stardom, Alexis' introduction to the mix, was also the catalyst that created the problems. In season 1, for instance, there are separate storylines and when the characters and threads come together it is in some cataclysmic, big pay-off episode like Blake's trial. But Alexis has to be in every single story: she messes with Krystle, with Sammy Jo, Steven, Blake of course, Cecil, even poisons Claudia against Krystle, and manages to even often Fallon marital advice, and of course to conspire with her. What was a more or less medium paced ensemble show turned into a hurricane with Alexis as its eye, but then it was easy for a story to lose steam if it presented no potential for Alexis. Mark, for instance, after Alexis brought him and tried to use him to break up Blake and Krystle, had to become her bodyguard to stay relevant. Similarly the writing team's desire to have her as head of Colbyco pushed Cecil out, whereas having him around for a season while she is by his side and is trained by him would have made more sense. Even Cecil taking Adam under his wing as revenge for Jeff defecting to Blake would have been more sensible.
