No, apparently I don't see it in the same way as you do.
The way you describe it, your characters will be far too powerful by the end of the game. He or she will be able to destroy any fiend in a single blow and that will ruin any kind of challenge the game has. If that was the case, yes I could care and I would agree that the game is incredibly unbalanced.
However, what I figure is... You hit level 20+, yet the monsters are still hard. You still need to enhance your skills in order to get stuff done because the game is still difficult at that level. If that is the case, you really are just bitching about a number and nothing more.
