Which heroes in Heroes of Might and Magic III are the easiest to play through the game with? And how can I determine the number of units in a stack?

1. Armageddon's Blade - definitely the most challenging campaigns. 2. The Restoration of Erathia - a bit more difficult than The Shadow of Death, but easier than Armageddon's Blade. 3. The Shadow of Death - the easiest campaign and the only one where you can set the difficulty level yourself.
