Fair enough, yeah. This is where I have had more luck recently with LitRPG books versus JP RPG LNs. Divine Dungeon, as an example, does a better job with showing the characters actively building toward getting stronger, and even when gaining extra knowledge regarding a subject they're flat out told they can't be considered experts at it with knowledge alone. Practice is needed to make things perfect. Compare this to something like Unwanted Undead Adventurer where the character has all of the theoretical knowledge, and can't pull off anything with it because he doesn't have the strength for it. Then he gets said strength, and can instantly do everything well just because he had theoretical knowledge of it. It's not terrible, but it's a little disappointing to read, a bit like what you're saying.
Stuff like that isn't a huge emphasis for me though. Mind you, if it gets too retarded, like Re:Monster, it gets dropped in an instant. If there's still good character interactions and development, along with world building, those can hold things up a series for me. At least until RPG rules get broken, like I said in an earlier post. Like a character "rejecting" level ups and skills because they're "cheating". Yet somehow they're still just as strong as their peers. No amount of world building or character development can let me ignore that level of stupidity.
And indeed, it's nice to just have a mellow discussion for once, thank you.
