Do cards that increase battle point accumulation also increase xp gain?

The Bounty Hunter star card is a battle point increasing star card for each of the four main classes:

The heavy also has an additional battle point increasing card, Defender:

These cards can be nice when the player is trying to get points for another class or hero. But I wonder: 'does this also increase the rate that experience points are gained?' That would make the cards more useful, because otherwise a player might get experience points faster with other cards if these cards didn't count towards that value.

Do battlepoint increasing cards also improve the rate of experience point gain for the player and his current class? Essentially do you receive experience points for all of the battle points you receive. Or are the two values tracked separately and battle point cards do not impact player or class experience points?
