The point is that it seems like medium is not in the sweet spot (it is easier than hard and harder than easy, but not the experience it should be , apparently).
Well, I'm glad you fell that way! It certainly is a major part of the experience, but not everyone thinks that. Some people just give up (that's what easy should be for). The game isn't as balanced as it should be yet, I'm constantly working on it.
Good luck!
