It is a very common and very wrong association that casuals like things easy while hardcores like things more difficult. They are actually very separate. There are just as many casuals who love challenge and do not only want SE to stop nerfing all the content but also want them to add more of a challenge to many areas of the game as there are hardcores who want the same thing. At the same time there are just as many "hardcore" players who want the content much easier so they can breeze through it and get their treasure and reach their goal as there are casuals who want the same thing. So stop with the casuals want it easy stuff. They are two seperate sets of opposing people and mindsets.
