Off peak hours are totally fine,trust me I am Greek.Lately I have even gotten RvR action at odd hours for the North American players.With the amalgamation of populations I don't think there is gonna be any US server left without action,peak hours is still when the heavy stuff goes down but I find myself always doing something no matter what time of the day I log.
