The fact that the scales might chip and break off prove that the scale armor is doing its job better than the cuirass. Because the scales are layered, they will absorb blows a lot better, so even if a few scales break off, there's still several layers underneath working to protect the warrior wearing them. Alternately, the best a cuirass can do to hold off a powerful blow is dent, which will heavily restrict the movement of the warrior wearing it afterward. So your whole point saying "if the scale armor gets hit too many times with weapons it will stop working" also applies to the cuirass--it applies to any armor in general. Obviously if a piece of armor gets hit too many times it might break. But the cuirass will break a lot more easily than the scales because of their respective designs.
