It makes perfect sense. Have you attempted to use Civil 3D for large projects? It simply isn't built for large projects and its performance sucks big time. You spend a lot of time managing how much Civil 3D objects are in a drawing. If your job is to simply add note type labels to the plans why should the user have to wait for Civil 3D objects, that should be static, to update over and over again, with no real benefit?
Have you tried to print plan sets of over 500 sheets with AutoCAD? It simply can't do it without a lot of extra unnecessary work. Former CEO Carl Bass saw a world of infinite computing power, but AutoCAD Sheet Set Manager can't even handle more than 255 sheets. An AutoCAD drawing can only have 255 layout tabs. What do you do if your project has 10 miles of roadway and 400+ cross sections sheets? You don't look to AutoCAD to get the job done.
Seems like Autodesk could have moved closer to infinite computing rather than their products being kept close to zero computing power in the six years that Carl Bass starting blabbing nonsense about infinite computing power (while not having software developers work towards that goal in the former flagship product of Autodesk).

It really makes no sense to use Civil 3D with the lack of work by Autodesk to improve Civil 3D's performance. Instead of getting speed improvements to the product we instead get our money for Civil 3D going to Infrasucks. When was the last release Autodesk bragged about speed improvements in Civil 3D? It's been a long time.
Civil 3D is simply used as a Roadway Design Software, Microstation is the drafting platform. Since AutoCAD can't do the heavy lifting required for the drafting job.
These opinions are mine and mine alone.
