Your favorite and least favorite monsters in Heroes.

Yeah, the only downside is that having over 500 peasants is just ridiculous. I've said it before – who are you going to conscript into the army? Who are you going to put in the line of fire from ballistas? What's the base growth rate? I doubt it's high. What's the cost of peasants? Exactly, it's too high compared to the income. Okay, so when you get 500 peasants, they'll pay off their debt in half a month, become free, and that's it. And then what? The problem is getting to 500 peasants in the first place. You can't buy them all in one day. Are you going to keep buying them every week? And then you'll get bogged down in income and expenses. The real benefit won't come for a while. Besides, if you have 500 peasants, the enemy will have a thousand goblins. Or skeletons. Or... or...
500 peasants is a significant force. It can take down more than one dragon. But you're keeping them in the Castle. That's not right. But as soon as they go out onto the battlefield, they'll die immediately. Who's to blame? What should you do? Here's what. Convert them into elite red archers. That's all. As you can see, peasants have only one path. Besides death.

Regarding the topic – any Cyclops/Ghost-and-Archmage, depending on the priority in the topic title. -.
Cyclops – for the animation, coolness, and club.
Ghost-and-Archmage – because they're sneaky bastards. And yet, I rarely play with either of them, so I mostly see them on the map, near mines =(
