Expansion packs nowadays need to add to the core of the game. For RPGs they tell an additional story. For first-person shooters, they give you new levels to explore and weapons to frag with. With real-time strategy, you get new units and new powers that add a dynamic play value to the game. However, with both this expansion and its predecessor, Heroes IV expansions only give you more of the same... and charge you $30 for the pleasure.

Does that make this a bad game? No, it doesn't, but it is a bad expansion. Unless you've finished every campaign and scenario in the original Heroes 4 there's very little reason to get this add-on (except maybe to laugh at the funny names). If you love Heroes 4 and too much is never enough, then by all means drop some money. Though, if history is any judge, there are many more expansions to come. Hopefully, those will be more worth it.
