Without giving major spoilers, the main issue I have is that the main character is getting too powerful too quickly and it makes their combat encounters not very satisfying to read. Another issue is that when there is a more powerful being in the story, it’s unsatisfying when they’re defeated (which isn’t often, so I catch myself looking forward to seeing someone who can be a match for the character) because it’s over so quickly, like the author didn’t want to focus too much on it.
