My opinion
Personally I love Overlord, that's because we follow the villain's story, something unusual in anime. The main element that makes overlord incredible is the yggdrasil power system (races, jobs, spells, items, worlds, guilds), Maruyama manages to give a unique characteristic to each character despite the cliches, this means that despite the huge difference in New world levels don't spoil the story.
There are two things that I personally didn't like.
1- "no level limits" the MC of this story is level 1000+ that makes level max(100) nothing more than garbage, which breaks the fun of the story a lot, since it doesn't it has a good development which is normal for someone who is not a professional writer.
2- the other is obviously the waste of the "Yggdrasil System" that shows levels (def, atk, spatk...) jobs, races, that lets us know exactly how character building works, but this new system is just confusing as it's not that informative.
Despite all this, congratulations author, you are improving your writing with each chapter, there are no good overlord fics, this is one of the few fun to read, so keep going :)
