Well the harder the dungeon is specifically only matters if there are not alternatives. Pharous Sirius is a great example. I always loved the dungeon and the nerf really didn't change much since the first boss was unchanged and that was the simple mechanics of the fight forces a dps race of a different calibur. But I digress, people refused to learn pharous really because there were alternatives and brayflox was faceroll able.

So if they are willing to make a dungeon that would rekt people and at the same time accept that people will rarely do it and will drop if they get it in a roulette. So that is really humbling since they have know going into it no one will do it and most will even hate it so they are technically wasting time.
