OP asked why people are complaining. I gave two reasons for it. They don't necessarily have to go hand in hand. That's why they're broken up by spaces, to indicate they're separate thoughts.
Whether problems in this DLC (and Skyrim's buginess in general) were from lack of caring or just an oversight, people have the right to complain about it.
Well it seemed to me they were in reference to the quote you included, how foolish I was to think other wise.
Anyway your quite right ppl have a right to complain just reasonably. Unless it's complaining about complaining apparently that's not allowed? What about complaining about complaining abou complaints, is that allowed? Lol
