"Restricting the Defiant to guard duty would be a serious mistake."Realistically, the Defiant should never have been going far from the station to begin with. If the whole point of the ship is defend the station and the wormhole entrance then you don't be going out on jaunts to star systems days or weeks away. We know why they did it though for story driven narrative, but it was still a dumb tactical idea.
