More Exclusive Enchants.

    The problem with Minecraft armor is not the protection levels.  It's the enchantments.  Since you can use protection with anything, there is no variaty in combat.  The solution to this is to add enchantments that can't be used with protection, or protection above a level.  For example, a enchantment that increases attack speed that cannot be used with protection 3 or 4.  You would loose protection in favor of attack speed.
