MRD wins. WAR wins. No contest. Overpower/Steel Cyclone + Berserk > anything.

Flash is your best tool for AOE aggro as GLD/PLD. Unfortunately it's a lot harder to hold aggro at a lower level because you won't have access to Shield Oath yet, but once you do it's faceroll easy. 'Til then, Flash and Riot Blade are your friend.
