The triumvirate paradigm doesn't work nearly as well in DS9 as it does in the other Trek series. First, there's the whole ensemble cast thing. Second, less of the drama takes place in single locations.
Nonetheless, it feels like there may have been some attempt to elucidate a three person grouping at the series inception: Sisko and two advisers/confidants. Of the remaining men in the cast, no one was close enough or important enough to guide Sisko's decisions. On the other hand, Kira was a necessary adviser and Dax was a long-time acquaintance and friend.
Now, the paradigm doesn't hold up well over time. The characterization of Dax was off, and the actress wasn't always up to the task (by her own admission). Dax makes a great comeback in season 6. In the meantime, Odo and Worf are much closer to Sisko, but their personal stories take over.
Even if Dax fell out for a while, it still seems that the series was intended to look like a man of color and two women leading the action, making it more progressive than other versions of Trek.
