Impressions of Heroes V, for those who have played it.

Yeah, it's an awesome GAME!! I just didn't expect the licensed Russian version to be released so quickly, and I didn't have time to upgrade my computer. I bought the disc, but my computer is still not powerful enough. But that's okay, I'll upgrade it in a week. For now, I played a little at a friend's place. Everything is great, but I haven't figured out how to split a unit into several units yet. Can you tell me (I haven't played much yet and I don't understand)?

Is there a Dungeon faction?

And when will the random map generator be available?
