Joan has entire existence have shifted to match Sherlocks. She doesn't have friends outside of Sherlocks friends. She doesn't have work outside of Sherlock work. She doesn't have a life outside of Sherlocks life. Even stories that should've been Joan's own (Cortes, Her sister) exist only to act as a foil to Sherlocks own life (Moriarty???, his dad). THE DYNAMIC DOESNT WORK IF ITS TWO SHERLOCKS AND NOT SHERLOCK AND WATSON.
