i got that different levels enrich your experience with the game, but without the easy medium and difficult ranges, the people will not be given the chance to build a foundation. I don't want to enter into a battlefield without learning the simple things first. Experience tops everything, and when that is taken slowly with varying difficulties, a player will be able to learn from that. Different levels can make a player learn something too, but without learning the "easy" before the "hard", they can never truly learn the value of working up the ladder.
