Yeah, a typical sign of a bad writer is the fact that they feel that their readers HAVE TO be explained what is happening in the world. It reveals that they've realized that their ideas are so weak that simply showing isn't enough.
This is made even worse by the complete inability to be concise. Every phrase or word that that can be cut should be cut. That is the first thing I was taught in a high school literature lesson. Once you've cut the fat, then you tighten the sentences, usually with multiple iterations. The end result is something that resembles the way that an actual human thinks and speaks.
There's no clear answer, a high school lesson answer might be a cookie cutter for things set in this world, biographies, real world novels, thrillers, crime books, but when you are put in completely distant fantasy setting, with customers who have no idea about the pathfinder series, you need some exposition, it's virtually inescapable. You can't just show everything through narrative, actions or the worldbuilding, because the game would be way too costly and require way more effort, something that can be prevented with just few words of exposition, instead of building a custom quest, scene of a humungous battleship destroyed across the desert of grazing tribes.
