Tactics for the Swamp (Fortress).

It's completely unclear why the first ones were removed without finding an equivalent.

But in my opinion, it's perfectly obvious. In Heroes of Might and Magic V, the concept of castles was replaced with the concept of RASS. And just as the entire third part resembles a colorful, mismatched zoo, the specific swamp castle represents the quintessence of this. What should be at its core? LIZARDMEN or gnolls? Since there are already creatures resembling a zoo there – it should be the Academy.
