Regardless whether or not you thought it was "good" or not, how can you claim there was no "moving" of the characters in an emotional manner? I cite the reconciliation between Ezri and Julian as but one example. There is a VERY clear evolution of that relationship.
There was no arc involved. One page Ezri frets, the next page they kiss and make up. It plays no role in the novel. And because it plays no role in this novel, it needn't be included in this novel. Save it for the novel where Ezri's relationship with Julian comes into play.
On a broader scale, this novel is ripe with exactly that situation. Things are brought up that have no bearing on anything else in the novel. The constant reminders of Quark's financial situation are but one example. They had no bearing on the events of this novel, yet were brought up by multiple characters on multiple occasions.
