Light mode isn't needed – there's plenty of it in Heroes 5; I'd like a reasonable hard difficulty, preferably with a non-linear strategy for victory, but at the same time, preserving the foundations of the classic Heroes (i.e., without mods that drastically change the essence of the game). Another question: can the map creator set the behavior of the AI he created in battle, or does the AI only follow the behavior that was initially programmed into it by the game's developers? Because, personally, my biggest complaint about Heroes 5 is the AI's frequent inappropriate behavior in battle.
