I'm of the opinion that the core Fighter should have access to Maneuvers and Superiority Dice, not just the Battle Master Archetype. I actually sat down and reworked the core Fighter progression a little bit, was easy to do. Basically give a couple of Superiority Dice and Maneuvers at second level and then another die and maneuver (or two) at the levels where the fighter would get the extra ASIs. The Battle Master would of course get more dice and his dice increase in die type.
Works fairly well.
