To OP,
What I don't understand is that you likely have hundreds, possibly thousands of hours of logged game time, but seem surprised that the game has become boring for you.
Most story/plot driven games have about 30-40 hours gameplay, and maybe some extra content for NG+. You wouldn't expect to replay a regular story given game repeatedly without getting bored. You have definitely got your moneys worth so maybe take a few months break and just check in to explore each new major update.
