The most recent one I've read was I Alone Level Up. It was okay. The manhwa was better though. TNE is still pretty decent for the most part other than that I still keep up with Rise of Humanity.
Your review of Gate of Revelation is kind of… prejudiced? Most of the things you've even mentionned have an explanation later in the novel rather than being plotholes and I honestly dunno why so many people (33 likes) actually agreed to your very specific review. I'm not sure why those minor things even made you rate it 2 stars.
If you really need "spoilers" (otherwise do not read this post): yes the main character isn't the only irregularity and it indeed doesn't happen rarely, also there's a difference between accidental ones and intentionally created ones, why the GM ignores that other ones existed previously is part of the story as well and it's related to what you assume as an AI acting freely. (end of spoiler)
I really don't remember the story well enough to comment on the specifics, but I remember not enjoying it very much.
Ah I saw you again reviewing about Arena and you're again assuming things which are wrong. For example here you assumed that the skills don't evolve even though that's never precised and a dozen chapters later the opposite happens. Really I don't think the blame is on the novel, keeping mystery is a decent plot device at worst.
