Mists of Pandaria had better alliance vs horde conflict than BFA, and that is all BFA was supposed to be about.

Mists had a build up with conflict to a final raid that took place in Orgrimmar. BFA was supposed to be this big war conflict but got squandered by stuffing it with Azshara AND N’zoth for some reason. And at the end of the day BFA ended up being a side story to push the shadowlands agenda.
