2 things here

1) nobody says dungeons should be hard, but there is also something to be said that dungeons shouldn’t be so damn easy and have such broken abilities like bloodwhetting that it makes the dungeon actively unfun for other people. There should be some element of challenge in them that makes them fulfilling

2) the casual content they shouldn’t have changed was things like alliance raids which were designed to be bridging content but they have been nerfed into the floor

Casual content should still offer engagement to higher end players and offer a sense of scale, EW casual content really does neither
