This thread isn't about giving us a challenge. It's about having content that lasts longer than a few days or weeks. I also don't believe that time sinks = challenge, I'm sure nearly everyone would agree on that.
As I stated before, though you probably missed it since you skipped to the end, challenging content is only challenging until we develop strategies for it. Even still, any content can be made challenging. Once your done with that content though there's no reason to do it anymore.
I'm all for difficult content, but it would be nice if there was some content that could keep us busy for extended amounts of time.
