The weakest castle in Heroes of Might and Magic IV!

Why... you can crush everyone with Barbarians even on large maps! That's what I did :)

No, that's not what I meant. I meant that this setup is the most optimal option for a quick victory...

We all actually play on large maps with the factions we like (I sometimes play with Barbarians on an LX map, and a powerful hero emerges by the end of the game - it's exhilarating).
