I wonder if people who have such difficulty with the narration of healing surges had similar issues with a one minute round? Or, did people just sort of hand wave that away and ignore the fact that there were all sorts of things that were supposed to be happening in that round, but not movement (because disengaging from an enemy, or turning a flank had its own rules) and simply concentrate on the short period of time that the die roll actually represented?
The thing I had a problem with was AD&D had facing rules, but if you're dodging around, feinting, and trying for a telling blow, you'd likely be able to have a wider range of vision.
I always found it weird that D&D dropped facing at the same time it compressed a round to the point when it made narrative sense. In 6 seconds facing a potentially lethal situation, you probably are concentrating in a particular direction.
