That is some accusation. Chalice dungeons for me are just places to try out your combat which are equally important to me as the environment in main areas. CD is more like a playground to try different weapons in and fight crazy stuff, though more interesting areas only come at latter depths i admit. Making the aesthetic of the Nightmare frontier a random tile set for something Randomly generated with a sky box to boot would be a challenge for even the biggest AAA studios.
It's exactly the random (not that random, anyway) aspect that's detrimental.
Boring room after boring room, with enemies dropped in, and often even copy pasted bosses.
Then you even have shit like the Defiled Chalice, which is textbook definition of "cheap artificial difficulty", something the Souls games prouded themselves not to fall into.
I don't care about the difficulty in and out of itself, in Souls games, i care about the intricate and unique level design, i care about the deep lore and interesting bosses, not just content for the sake of content.
The difficulty is a tool to push you to be creative and try new things, to explore and feel uneasy, not just a checkbox, like they started selling with DkS1 PC, and their "prepare to die" bullshit campaign.
It's a mean to and end, not the end itself.
And i criticized Dark Souls 2, for having too much content, but not enough polish on the individual pieces, and although the main storyline in BB is pretty great and polished, the Chalices feel exactly like that to me, padded content.
I would've much rather preferred a singular, well designed level, called "Tomb of the Gods", with some of the unique bosses we see in the Chalice, but designed as a normal level, with the nice complex level design, instead of having to see the same room 50 times, and open a majestic golden chest, to receive "Blood Ritual (3)".
Full disclosure: I also can't stand "randomly generated Rogue Likes" like, say, Rogue Legacy.
