Not sure what's worse: People caring enough to complain about your gaming habits, or you caring enough about their feedback to create this thread.
To answer your question though, games aren't usually designed to be plowed through effortlessly. By playing on easier difficulties there will be less tactics involved and several gameplay aspects (such as taking cover, using the terrain to your advantage, inventory and ammunition management, figuring out your opponents, etc.) will become obsolete, or at least less vital. Essentially, you are turning the game into a movie with slow story progression and no intensive action.
