The whole purpose for nerfing everything is to make end game content more and more difficult and require more and more of your time invested. They do this because new content costs more than anything in the game to produce. They are looking more at the financial side of the game and not creative quality and quantity. Players have gotten so good at the game and always finding the most efficient way to complete content and bowing through it too fast. I think we can all agree that we would be willing to pay for more new content and still allow us to have some sort of power fantasy. They are struggling to balance the amount of new content and difficulty of that content to maintain a player base and completion percentage.
