And if it's a specialist in attack, then death to all! And even though Orcs are weak, they are the cheapest at their level!
That's true, but you can also overspend: there are no money problems in Heroes 3, and you'll only be ahead in building by a week - BUT THEN you'll remember that week for the whole game.
Building Monsters is very easy, but Cyclops create problems.
I always play as the Queen for Dungeon, and on average, I build everything by the 3rd week.
