Because the way I see it Universal hopes to make Epic Universe successful and more people will prefer it to Walt Disney World because it will be better with rides that actually work
Epic constantly has 1-2 ride delayed/closed ever since the opening. The thing is most of Epic rides are outdoor that cannot be operated during thunderstorms, which are frequent in the Summer. And one of the indoor ride, Battle at the Ministry, has delayed quite often, which if it happens at the same time when all outdoor rides need to be closed, then it becomes a disaster. There are many reviews that complaint about getting to do just 2-3 rides all day because of the closures such as this one. Epic is still experiencing growing pain and it will take Universal awhile to sort things out with the technical issues. But designing a theme park in Florida with mostly outdoor rides is probably not a good idea if they want to provide people with rides that actually work.
