Why is there this assumption that the Borg would all out attack with everything they have? They never did with the Federation. All they need to do is assimilate a few ships to grab anything technologically worth having along with the lifeforms. The Borg maturation chambers already suggest they can clone new drones as needed.
Borg seem to attack if they sense a future threat.
Hence why they went out there way to attack the federation even though it was half a galaxy away from its space as it could see them as a future threat.
The Dominion is far more powerfull than the Federation so would elisit a stronger response.
