I'm no sure what set up Worf and J. Dax to a similar extend as that episode did the latter with Bashir.
1. Curzon’s past interactions with the Klingons carrying over to Jadzia.
2. Worf’s holdover feelings for Troi, after ending their relationship due to being told of the anti-time future. Due to his relationship with Trio ending early, he finds a brunette woman in Jadzia to resume that relationship in a sense. And of course, Jadzia meets a tragic end like Troi did in the anti-time future. I don't think there are any hard feelings between Worf and Bashir like there was with Worf and Riker in the anti-time future.
Both tough, both honorable, both warriors, and both with a deep religious faith... maybe they're more similar than you think.
Kira wears her emotions on her sleeve, whereas Worf maintains an ice cold exterior.
Kira still worships the Prophets, while Worf made it clear that the Klingon gods were dead and killed by the Klingons as they were too much trouble. And Worf has to endure any insult of still believing in religion, whereas Kira doesn’t and makes her opinions known.
Worf fought for the restoration of his Klingon house, whereas Kira was fighting for her life and for the freedoms of Bajorans during the Occupation.
Not discounting their similarities. Just pointing out what makes them distinct as individuals.
