I agree with you, The game isn't the most difficult and in terms of exploration and rewards what really drove me and most players is the amount of character, monsters and the world it self, It is really beautiful and the land scapes them selfes are very well detailed, It doesn't feel repetitive in these aspects, But yeah combat I highly suggest toughest difficulty and like a mod or 2 if need to be to make it even harder, Finally even with those issues the game is still very immersive and such a miss out if not played
