What is Blizzard's issue recognizing a lack of endgame?

Lol, self-contradiction in one sentence

The “ugly” started at S2 and culminated with the Pit. The game was much better of without it and when had 100 levels. Felt like a journey to complete, not a homework followed up by a task to repeat all the time

The problem is they refused to “complete” the last phase of the game as was initially designed, and decided to create a new one (from scratch)
