Why is everyone so sure Blizzard would not do another Cataclysm?

To start, this is not directed at any specific leak but a general concept. I have noticed that a vast majority of the forums seem convinced that Blizzard would never do another cataclysm on the grounds of "There was a lack of end game last time because of how much time was spent on leveling zones!"

With the new world scaling tech doesn't this kinda defeat that statement?

I didn't find the right solution from the Internet.
