Which units would you like to replace or add?

Yes, the titans will need a sword, and it would be cool if they summoned it into their hand before attacking. I think the Djinn are very good, even better than in Heroes of Might and Magic III. But I really don't like the Gargoyles; they were much better even in the third game. Of course, the Gargoyle isn't the strongest unit in the game, but why treat it so badly?
