Some type of "enemy danger indicator" is a must, especially for people not familiar with d&d and typical monster difficulties. I agree that this doesn't necessarily have to be a level indicator. But I worry your suggestion could be difficult to implement...could you tell the difference between a level 7 vs 17 fighter from a cutscene?
I strongly disagree. Let the context suggest which characters should be a poor idea to cross. And let the player pay the price if he goes out of his way to ignore the warning signs.
It worked flawlessly for years. Not sure why D/D would now suddenly need to flag enemies by levels.
