The ranking system makes very little sense. its not even explained properly and we are supposed to figure it out on our own. MC continues to make the same mistakes over and over again and doesn’t seem to learn. The author also likes to show the characters indecisiveness on simple things such as leaving a tavern and not being able to decide left or right without a few paragraphs of internal monologue.

Lastly, health and his resources are supposedly infinite. While others die in a single hit to the heart, Michael seems to randomly be able to survive fatal wounds, and other times overcome the situation with his willpower. At the same time he will have barely any points in constitution and is being played out like he is a brawler/tank type class.
