We tried version 1.7.9 of the generator with the new templates in the game with Yavgen – there was still a mountain in the middle of the starting zone.
According to Moza, the new generator makes the terrain more balanced, but something needs to be done about the mountains in the starting zone.

Nothing has changed regarding the generation of "mountains" and other obstacles (which are obstacles), and it couldn't have, as I didn't change any logic other than removing portals in version 1.7.9. Even the reworked road algorithm is just a transformation of recursion into a stack. That is, the algorithm itself still does the same thing, only it doesn't make nested calls of great depth; it stays on one call.
And I only generate maps using version 1.7.9 and the old templates up to the latest edits, and I don't see any changes regarding obstacles; it would be strange for me if it were otherwise. As before, there are a lot of mountains in empty areas of the zones. Previously, this didn't bother anyone; I don't understand why there's such a fuss now. No one has ever raised the issue of the probability and logic of placing obstacles. The zones in the templates are empty. I see how much unfilled space there is – nature abhors a vacuum.

There are two options: improving the templates to a reasonable expected value of objects,
or revising the obstacle generation algorithm, which has remained unchanged since the very beginning of Heroes of Might and Magic. There is also an option to generate maps without obstacles – they will be clean fields.

In my opinion, the templates need to be improved
