You have to be careful not to confuse Battlemaster with a Realm vs Realm game. It is partly that, of course, but it is also mainly a PvP game.
You see many character who drag their realm into an unwarlike stance after gaining power; this does not mean they are playing non-competitively, on the contrary. This mean that the best path to fullfil their ambitions resides in not going to war. This is perfectly legitimate.
I agree that "serious, non-competitive roleplaying" is contrary to Battlemaster, although it does not bother me as such if people find fun in playing that. I disagree, however, that the same should be extended to realms.
