People don't want a challenge. If this were true people would run content at the minimum iLvL required for it. Or they would actually run PS when the get it in roulette. All people really want is that next "trophy." They want some form of recognition for completing a perceived challenge.

If you really want a challenge like you are clamoring for, then go create a challenge. Find a FATE boss to solo, run a dungeon in bikinis, something. Don't pretend to want challenging content when all you really want is for other players to say "omg, you're amazeballs, you did [insert here]!!!"
