Garry,
This is very true. I have seen these shortcomings of rubrics offset a very few times by institutions providing for the academic freedom of the expert instructor to provide an 'open' category worth 25%. The category does require a detailed explanation, but providing detailed, constructive feedback is part of the job anyway. So this is not an issue with instructors who are really teaching. Thank you for sharing this insightful contribution.
