This topic is already inherently for hardcore players, so if something is to be done, it should be done to the fullest extent.

I set myself the task of devising tactics using starting units on my home territory, and I accomplished it to the fullest. Because in the early days, it is NECESSARY to venture into dungeons, and if you don't know a precise and well-thought-out tactic, you can suffer unbearable losses on the highest difficulty. And I don't think this is hardcore gaming; for me, it's a necessity. As for the other ideas – for non-native territories, etc. – that's no longer a necessity but rather hardcore gaming. If anyone wants to, they can come up with something and might even be kind enough to share it with others.
