An example of what?
Did I hurt your feelings stating an obvious flaw of your mod?, in my opinion, indeed, perhaps I am wrong but I am just a player of your mod, giving feedback to improve it, you can ignore it or think about it in more depth.
You need to understand the difference of "easy/hard" and "grindy", also you need to understand the flow of 7Days to Die and how to catch the interest of players in the late game. In early game we are plebs in rags, but soon we are fine, we solve easily the feeding, the house, the anti BM horde base and the game gets stale. With your classes system you can give some purpose to the player in late game but you hide it behind a grind wall, and perhaps you will lose the interest of the player in the meantime.
I am demanding nothing, I am requesting a change.
