With all due respect, you don't understand how running courses work. The course length has to be certified. Changing the path of a course means a new certification has to be obtained. That doesn't happen overnight. The course through Epcot has been this way for years, they aren't going to change it unless absolutely necessary. None of this happens in a vacuum, the running course was taken into consideration when erecting the construction walls.
Nothing was spoiled here. For reasons no one else seems to understand, you're really making a mountain out of an mole hill.
