Which units would you replace in the Sylvan castle?

Regarding the imbalance, I agree with you, but we're not planning on changing anything in the live game (and we wouldn't be able to anyway). It's all just... a dream...:rolleys:
Ents should be made like in Heroes of Might and Magic III. In 3D, it would be a masterpiece! And I would replace dragons with phoenixes. Starting with Heroes of Might and Magic IV, they feel more fitting.
