Of course, when the producers on DS9 felt they can break the unwritten rule whenever it suited them. It must've been brilliant to learn of all of the races of villains Star Trek officers has ever encountered, never thought of firing at the propulsion units, and then ramming ships at these Starships. It's like the conceit of superheroes wearing capes, we know in the real world its a detriment for anyone to wear such a thing if they tried to fight or save someone, but in the world of the character it's safe. Since TNG some of these boneheaded producers had been toying with this idea over and over and over again because in their minds the neck portion and the propulsion units are vulnerable for combat, but failing to understand if they're asking those kinds of questions than maybe they should find another television show to work on other than Star Trek.
Galaxy Class ships are state of the art and can sustain incredible stresses in order to travel at great lengths of the Galaxy and whatever is out there they happen to encounter. Also, from what I'd seen on TNG the Galaxy Class can move pretty fast, and it still can move quickly with one operational propulsion unit. It should've taken more than what the Jem Hadar had done to destroy that ship. But like what was done on TNG with Worf, he had to get his ass kicked by a woman or someone to get street cred they were tough.
