As a new player, I'm still figuring what alters my score and I notice that flying into a furball in B24s and killing enemy fighters, protecting other bombers, or killing CVs all night, does little to your score, while guys who are bombing fresh towns alone, with no enemies around are getting higher scores, they are also ruining it for the team, because sections of town then pop when the CV has arrived and is trying to take the town. Seems you have to learn the scoring to increase the bomber scoring, I would agree.
