That leads me to ask: what is your favorite form of PvP and why? Old school outdoor PvP for chaotic tag and run? Arenas for the emphasis on skill? Battlegrounds for the variety and challenge? Outlands outdoor PvP for occasional PvP fun during while soloing? Or just straight up PvP servers where you never know when your next ganking is going to materialize from behind or come blazing toward you from afar?
