After 60-70 hours of it I have to agree with you.
Maybe I'm just easily entertained.
The biggest problem with it was the repetition. Every new city, new (original) quest was a breath of fresh air.
Take out the cookie-cutter idiotic "radiant" generated quests. Have less meaningless caves. Maybe less, but better quality quests...
Make the caves and the dwarven cities much smaller. I can't bear to spend hours in a fucking cave, going through similar looking walls. More interesting stuff in the open world, less in dungeons.
