The main point of refactoring would be to get rid of code duplication. If I remember correctly the producers use a lot of the same code because the pages are identical.
I think it's good to be able to preview an evaluation with instructor questions before it's been assigned to a group. I'd prefer "Sample Instructor 1" and "Sample Instructor 2", because my initial reaction to seeing Aaron and Steve was that something was wrong. We do also need to be able to preview evaluations that have real instructors. All of our evaluations have real instructor from the outset. The preview of assigned evaluations shows an instructor exactly what a student will see. We could show the first preview if there were no instructrors yet and the second perview if there were, with only the source of the instructor name stings being different.
