Well, I've already joined and requested a battle against the Wizards; it's interesting to see what kind of army he has. The victories in his other battles are quite obvious, at least to me. And I've already played the battle against the Efreet on approximate settings, without morale and luck – as a result, I lost a couple of dozen more Gargoyles.
In principle, for such a short playthrough, only 2 saves are really important: the Wizards and the Phoenixes near the portal. The other battles, considering the surrender of Gargoyles, are of course obvious, I agree, but it's still more illustrative to look at the dynamics of the playthrough.
