EDIT: Now that I think about it, the narrow ramps that you see in the campaign are banned for competitive maps because units like Dragoon will simply never go up or down one unless babysat the whole way, one by one, clicking a few pixels further with each move command so that the Dragoon doesn't go backward. Brood War is full of unbalanced and unworkable mechanics and was fixed not by Blizzard patches, but by literally professional pro map makers.
I thought it was pretty good, and more than enjoyable, when it came out 19 years ago.
Now...I don't see why they couldn't have included it as a toggle-able option. I know that I've considered trying to build updated versions of old games, and when thinking about how to do it, that seemed like the best choice.
This is precisely why RTS as a genre pretty much died.
