I might have missed something here, so feel free to correct me if I'm wrong, but it seems that the spiked shield can be used as a light, off-hand weapon in two weapon fighting, dealing 1d6 damage AND giving the +2 shield AC at the same time. Erm... why would anyone not take this? It seems very overpowered to myself and my dnd test group. Surely it shouldn't be giving its AC bonus when used as a weapon like in the old days? Weigh in chaps and chapettes!
