Think real hard about what you just said. "Compensate for potential time loss due to encounter opposing faction players".
Isn't the entire point of PVP servers or War Mode to encounter opposing faction players and FIGHT them? How is it lost time if that's the whole reason for even being there?
Do you see? The entire premise of War Mode having a PVE reward incentive is jacked. Wrong. Bad. War Mode shouldn't have ANYTHING other than PVP rewards, if for some reason just being able to fight other players isn't the reward itself.
