If SF designed the Intrepid class to be a downsized Galaxy class,
I'm pretty sure it wasn't seeing as I hear that was kind of part of Voyager's premise and all
Where do people even get the idea that the Intrepid was supposed to be a mini-Galaxy, the only ship I would think would remotely qualify as a downsized Galaxy would be the Soverign-class.
The Borg are a formidable foe, taking down even something really small like a sphere is a good job.
So I guess the Soverign is more badass for taking a sphere out with only 4 or 5 torpedoes
