Disappointing on every front. In a weird way it's the inverse of WoD, which was an expansion people wanted to play but quite literally couldn't. BfA technically had so much content but ultimately created an experience that had you wanting to engage with none of it.

BfA really highlighted the unwieldiness of balancing external power systems with consistent content releases. Remember, Legion was only able to somewhat accomplish both by killing WoD in its tracks and siphoning its development time.

Tearing through 3 to 4 expansions worth of storylines and the resulting whiplash and unsatisfactory story beats also works against the game, but at the end of the day the miserable gameplay experience is what really drags it down.
