I think most people export individual objects to fbx and do composition in unity since you need to do shading and lighting in unity anyway. Once you get the fbxs into unity, it's pretty fast to modify a model in blender, re-export, then unity will pick up the changes and they will show up in your scene. You can try importing the .blend file directly in unity as well, but I don't think it's very well tested as a workflow.
