It's fine for it to stay difficult. What Blizzard has utterly failed to do consistently is:
1. Implement fights with mechanics that do get easier with more gear. Soaks don't really.
2. Let people overgear the content.
If it's going to continue being shit design with almost all player power gains in an artifact weapon and set bonuses / trinkets so gear doesn't really matter, then yeah, nobody wants to spend all their time doing shitty content.
