I'd imagine that Scholars win the day here. They can just enjoy Cleric Stance fighting while their fairy does the healing. Dragoon and Monk will lose some of their damage due to hitting the enemies in the front. Paladins, however, are in no trouble whatsoever unless they decide that fighting in Shield Oath is a good idea. Switch to Sword Oath and their damage is sufficient. Throw on some Strength accessories too and they melt things almost as well as a melee DPS hitting just the front(450+ Strength is pretty fun as a Tank).
