The one arm armour aka manica was pretty popular in Roman soldier armour and gladiatorial armour. I think it was basically intended to protect the "sword arm" since that's the one that would be doing all the swinging around. The other arm was expected to be protected by the shield.
Then my memory is getting rusty. I have every nu52 WW issue. Need to go check out those panels again. The armor is def sweet but a little busy. I can see why DC wants a simple design yet they can still achieve that with a battle skirt and keep the current costume basically the same.
