A grinding game is supposed to be a more or less unlimited game, so it is normal that the maximum is a very very hard to reach task. And also it makes the game a bit more interesting, by getting the health adjusted to the overall level, getting high or even maximum enchanted armors ain't a usual thing anymore, and the overall level does display the true progress of a player.
