Which new units did you like in World of Xeen?

I agree about the "snipe" strategy. The Dracolich is the strongest creature in the game!
In my opinion, Ghosts are an attempt to diversify the ways to win in the game, an idea taken from Heroes II. However, in terms of usefulness, I don't think anyone will be recruiting them. First, it involves destroying an entire town, which takes time and resources.
