False. Fun is a goal. What you fail to understand is that "fun" is subjective and what you find fun others don't.
So what you are really saying is "fun for ME is no longer a goal of Blizzard's. And it shouldn't be. Why? Because there are millions of others who play and many of them don't find fun what you do. The actual goal is to make the game as fun for as many people as they can knowing they will never make it fun for 100% of the people.
