The Skyforge site has a new developer blog post that lays out the details of the Battle History revision that will be coming along with the Aelion's Call update. All players in a Pantheon with at least level two can access Battle History which gives statistical information about group damage, damaged received, enemies, length of battle and more.
In the Battle History, you can find statistics for each combat you participated in, whether it was a tough PVE or PVP battle (or an easy one, if you want to brag)! You can learn from your team mates as well – you will get as many details for their actions as yours! In its initial version, the statistics are kept until you exit the game, and reset afterwards.
