New creatures for Heroes V.

By the way, I was thinking about creatures like that. That is, how could creatures like the ballista creatures from Heroes 7 and others be used? A) They could be ranged attackers on towers in the corresponding cities. B) They could be made into stationary neutral creatures that only appear in specific buildings. For example, add the gnomes' dragon cannon from Heroes 7 as a creature in their treasury. Mapmakers could use this creature at their discretion, for example, by adding it to the army of a hero who is guaranteed not to have certain buffs, such as certain artifacts, or by placing the creature as a neutral that will never join.
