I think it could work like this. In theory, it's possible to organize a tournament using save files generated by the tournament organizer, but it would be implemented as follows: 10 (20, 30, 50...) save files are uploaded. Participants agree to choose any of them and play. However, this means that players can download the save file in advance and study it in detail. How does a save file differ from a map? It has a clear, predetermined set of spells, troops, and other elements, including the hero's skill tree. But then it's not entirely online, but rather a semi-offline, semi-online experience. And the charm of unpredictability and the unknown disappears... In theory, it's possible to create or modify existing maps and upload them somewhere. Maybe we'll get around to it someday. But it should be maps, not ready-made save files. And later, if there are enough people interested, we can hold a special tournament using those save files.
