Battle Points is a statistical value that serves as an indicator for a player's combat abilities and their cumulative experience over time. Its formula accounts for various statistical markers, such as kills, teamkills, deaths, KDR and hours of playtime to create a system that changes constantly based on the player's performance in battle.
Battle Points are not meant to be a fixed value. For every additional siege where a player performs well, their BP will increase, and vice versa.
It is derived using the following formula:
Playtime is measured in hours (most sieges lasting typically for one hour). Although unlikely, it is possible for BP to become negative in the case that a player's amount of teamkills is greater than their proper kills.
