You need to keep the Champion maneuverless. There has to be a simple martial(Champion) and simple caster(Warlock) for those people who don't like or want complexity, and I've run into a number of them over the years.its a great start, I would want better manoeuvers for higher level use... but that is a GREAT start
I even made a thought experement with the base fighter only ever getting d4 or d6 and the battle master gets the upgraded dice.
it sounds good
