(Hero - Rogue) in Heroes 4

At least it exists in the 4th game. And even with it, the whole world feels small because it's completely absent in the 3rd game. Which I refuse to understand :) How can one live without a caravan...

It's very simple - in the 3rd game, it's not needed because the units have an infinite movement range; the main thing is to build a chain of heroes ;) And accordingly, troops can be transferred without a caravan. But in the 4th game, both heroes and units have a limited number of moves. You can only transfer a hero's tomb through a chain. And in the 4th game, you don't really need a large army - at least in offline mode.
