Meh I dislike the "difficulty" not because its hard but mostly because its tedious. Just take a look at GM vanguard alerts they are an absolute joke but enemies are just ridiculously tanky that it just becomes boring to do. I think the game started going wrong when around 3.0 subclasses came out and it just became worse as we were just trying to stack as many DR and damage buffs as possible. So unless you are always rocking DR boosts in endgame now you can get taken out very easily while when you do have them you are basically unkillable but at the much higher end so are the enemies basically. Its not a surprise the most popular armor set bonuses are ones that just give you more DR. You compare this to D1 and even in the highest end content you could at least take a few hits before going down mostly because the enemy density was a lot less and managing enemies with just shooting was much easier and fun. Now you don't manage anything and just spam whatever instant nuke ability you have that clears the room. I think most people that complain about the game being too hard atp usually are complaining about timers or just modifiers that make the game more tedious than engaging. Sort of a problem with challenge customisation is that its mostly "how do I make this activity the least annoying as possible."
