When you don't meet the requirement of a 16 armor shield it gets turned back to half of that amount, making 8 armor. So this one would be just as good as a max AL shield of which you don't meet the req.
Therefor I'd say its pretty useless, because people tend to prefer other skins and always have a few atribute points to put somewhere, prefering a shield with at least some requirement.
But perhabs someone finds it fun to have one of these and pay 5-15k for it, but I doubt it. Though I must say I know jack shit, so you better get some other pc's
