So I am all about decoration.
When the pict DLC was out, it was okay due to the introduction of the pets for decorations being missing.
It was “bad” but more or less okay.
Why are there no more decoration pieces?
IMO the main reasons of the DLCs are different armor coming with different stats, slowly covering each armortype+resistance+attribute combo, new building stuff and most importantly (as I tend to run around in encumbrance gear anyway) new decoration pieces to go wild with these!
Building looks at least a little similar to khitan and armor does so too.
Sure, there are new pet skins - but there are people who simply dont use any companion. (I dislike dragging a pointer with me.)
At least katana decorations or similar could have been added. Or decorative armors. Heck, even all the armor which gets introduced with each DLC might be a decoration itself!
A few lights, a few statues or similar on top and one only needs a few additional decorations for the package.
