This has already been discussed in the thread, multiple times. I don't want to use the NCF core for NHF yet.

What is the reason for this rejection? If there is a tool that can significantly expand the range of specializations, why not use it?

Besides, not all battles can be intercepted.

Okay, let's approach it from another angle - the creatures in the hero's army change to improved copies automatically, and he constantly moves around with them. They only change back to the original creatures when meeting their own hero for an exchange. This can be intercepted much more reliably, right? :)

P.S. If not all battles can be intercepted, then what about specializations like those of Hafad and Fiona, for example? Their specializations are directly tied to intercepting battles.
