No, we don't need a Swamp faction; it would just be a rehash of the 3rd Heroes of Might and Magic game, a pointless relocation of races. We need to show some imagination and come up with something new. For example, in Heroes of Might and Magic IV, they replaced the magic system, giving each castle its own unique magic. The heroes were also fully-fledged units. In Heroes of Might and Magic V, they mostly took elements from the 3rd game: monsters, castles, etc. They did improve some things and change others, but overall, they just copied the 3rd game. Of course, Heroes of Might and Magic V is a good game with a decent balance of power, etc., but the latest expansion, featuring the Barbarians, again brings back the same familiar faces.
