To be fair, plenty of devices have sustained damage or been cut in half, especially in S1 and A's. Anything can be broken if it is hit the right way, or with enough force. And were the Strike Cannons of Erio and Vita actually broken? I couldn't tell from those limited pictures; just that Vita and Erio were out of action (and Vita did break Karen's sword).
As far as other mages, well, these are our heroes. Short of introducing new ones, we work with what we got. Out of all of them, it did make sense for Hayate to have a new spell like an iceberg. I don't see much how Nanoha and Fate's magic would do something like that.
But I did suggest the cyborgs should have been brought in. Hell, converting magic to physical energy is something Otto does naturally.
