My stories are Webnovels, so they are always long since the plot, characters, and world building are vast. Perhaps it depends on the type of novel that you are writing. There are some standalone novels that only has 50k words and they are good.
Thank you for your opinion. For now, I will wait at least a month to see if the result of this new billing is good. And I have to talk to my patrons too about this possible changes.
