Quite the opposite. Their games are uniquely suited for Durlag's Tower/Watcher's Tower-style DLC - that is, adding new areas to the world map with higher production values and more possibility for craftsmanship than that of the rest of the main game (where a certain quantity is necessary). With 1-3 classes/races added that tie in to the themes of the new area.
This actually already kinda discussed by Owlcat iirc. Basically their main game is so enormous, that adding heavy content to the main game would break all sort of progression balance and just make the base game even more bloated than it already is so they are reluctant to do that. Companion with small quest is fine, a small additional dungeon is fine, but mini expansion is really hard to without breaking balance progression wise.
Regardless, I am just not feeling it. Maybe I will buy it with 50% discount or something. I want shifter because I am a sucker for nature themed stuff but the rest of the DLC is just kinda meh for me. I wouldn't mind Citadel style quest but the quality of base companion is just not there. Through the Ashes was OK I guess? But the twist after the 1st part is not really exciting either. And new companion is 100% a bi shifter guy, and considering base content companion quality, not really interested in that either content wise, I just want the class.
