Battle Power issue in New Genesis.

My gf has much better gear than I do and a BP of 1404. My BP is 1310. We are the same class Hunter Techter and I'm hitting melee just as hard as she is. My weapon has no fixa. We're not sure what's going on. Any ideas?

Battle power is calculated based a number of factors, not all of which are related to attack strength. It includes defensive stats as well.
