It's a mistake.
What makes it worse, they hyped this for 17 months only to deliver "new" content that borrows aspects of old content players dislike. The ratio of effort to rewards seems messed up, too. There's better alternatives to get better gear than what you'll get here.
I'm not as upset as others about it though. I already expected it to be like this. The only thing I'm upset with is that the developers proved that they learned nothing from past mistakes.
