I think the thing that bothers me the most about this anime is the way that Elymas seems to be unable to use his common sense or any knowledge that he gained from living in that world for his entire life
I don’t know if it’s because I recently read the manga just to see how badly the anime adaptation was trainwrecking the pacing, but the impression I got was that the world’s “common sense” about the game mechanics is often absurdly wrong.
Heavy Knights are considered a useless class when they’re actually completely busted, for example. So Elymas seems perfectly capable of navigating the non-game aspects of the world using the knowledge he gained growing up as a noble. But when it comes to classes, skills, and game mechanics, he trusts his past-life knowledge instead. Because the people of this world clearly have no idea how to properly optimize any of it.
And now he’s finally starting to realize, “Oh, wait, I’m not necessarily the only person who can be good at this.” Honestly, that’s pretty refreshing.
