The level of detail in Broken Shore is non-existent. It also has no new pet battles, new AK ranks have no story, new order hall missions have no backstory to them. It is also the first time ever that "rare" and elite missions give the same amount of rep for completion that regular ones do. Never before has this been the case in WoW. Moreover, they advertise as content perpetuating the reputation grind and by moving faction mounts to an RNG model.
It all spells "rushed" and "unpolished" to me.
