With all the editors I've ever worked with, when they find a problem they simply say "fix this," and leave me to deal with it in my own way.

So you're quite right. They're looking for writers who are professional and cooperative, but a good editor also respects the individual writer's creative process. Plus, quite frankly, they don't have the time to do your work for you. The days when the acquiring editor went through a manuscript with a blue pencil, acting almost as the writer's collaborator, are long past.
