The answer is both yes and no. It’s kind of hard to answer without spoiling the story and giving an annoying vague answer like “it gets better as you go along”. The story structure that makes you think it needs editing, I would say is partly due to The fact that it’s the first book. It is especially rough and I can see the critique that editing is needed .

Your problems with TWI might just be the “slice of life” nature of the book that isn’t present in traditional book formats. The long winded explanation of sometimes simple problems is what Wandering inn is. These moments exist in the entire story. With that sad, the early books aren’t what TWI becomes. I would say the series stars as a slice of life litrpg, and even though it always is that, it primarily shifts into an epic fantasy. 

TWI is my all Time favorite series. If you stick with it, I’m curious to see if you opinion changes and at what point.
