I think we can summarize a few things:
1) It would be good to make some concessions for lower game levels: in my opinion, the fact that the first battle is the same for both the Hero and the Recruit is not normal.
2) I'm concerned that the same first battle actually fixes the Hero's progression: without machines, it's impossible to win it, and using them is practically forbidden.
Otherwise, the impression of the scenario is more than positive; thank you to the author for this pleasant gift!
2) I wrote about the reasons for this above. The only thing I can do here is to see how I can change the stat increase due to the "Armored" skill of the enemy hero, for the outcome I am calculating. And the machines for the Orc are already laid down by the map author as a "must-have" for the Orc.
