With the current version of this feature, when you leave a faction PvP area, a timer keeps you in PvP mode for 15 minutes; however, the testing phase revealed an issue, where in some cases you could get a erroneous system message saying that you're are safe while the timer is still keeping you in PvP mode. We will fix this bug as part of a general PvP revamp to come later; in the meantime, to avoid delaying the patch, we will decrease the timer value to keep you in PvP mode for only 2 minutes.
