Placing all the nepotism aside doesn't change the fact that her character's been one-note and directionless without the incessant need of a title.
This alone wouldn't be horrible if there was some creative insightful look into who exactly is Charlotte without a title? Maybe could've had her rationalize that her entire existence is meaningless without one, because, how can she otherwise live up to her Dad's legacy without always being on top? It would a nice tidbit to give her character purpose and some depth.
But Vince and these writers probably don't even think that hard about all that beyond surface level impressions and whatever A to B destinations they got for them instead of the journey.
