Mayor of Noobtown: Do the litrpg aspects get explained better?

I've been trying to push through the first book of Mayor of Noobtown since it's so heavily recommended, but I'm continually put off by how poorly it seems to integrate the idea of an RPG with an actual reality. For instance somebody said the MC must be a warrior because he parried with his blade. I'm struggling to reconcile what that means. Is "Parry" the skill (visually) distinct from the physical action of parrying a strike? Is the action of parrying somehow impossible for those without the skill? Is everybody in this world fighting by mentally selecting skills from a list rather than actually doing anything with their bodies? It feels like there are some possible explanations here, but the book would rather not explain because then they would have to be consistent about it.

This has just been the worst explained example in this vein. It seems like it tries to pretend it's just a game, with entirely gamelike rules, while ignoring that reality is a lot more fluid than that. Other stories in the genre I have read (DCC, PH, HwFwM, etc) all seem to do a much better job with managing this relationship explaining what it means for somebody living in the world, but many of them did have some similar hiccups toward the beginning. So I'm wondering if this is something that improves, or if this maybe just isn't for me?
