Then don't play on Normal?
Problem is, if the normal settings doesn't follow DnD rules, what will make the hard mode follow it? Ennemies will be HP sponge, they will have more spell, damage, etc, it will NOT be closer to a DnD experience, it will just be harder to play.
I want a DnD game that feels a DnD game, the challenge for me is included in the RULEBOOK. I don't want to much powerful enemies, I want rules that follow what the game is supposed to be based on!
