Booty cheeks but what did we expect

It feels like everytime a author doesn't know what to write they just shove everything into the last 15 chapters and call it a day. like can we get more back story and more internal conflicts? there should be more conflicts in general that cant be solved with power alone. the lack of obstacles and revelations is disappointing. Its become such a common trend i cant even be disappointed at it but myself for expecting more smh
