Which units would you replace in the Sylvan castle?

Ents definitely shouldn't be removed! They are purely Elven. Elves and Ents, Ents and Elves, Elves only need Ents! Don't remove them.
But Druids, in my opinion, are not essential. Instead of them, you could put some werewolves, for example.
TO "Player": it's written, "just my opinion, don't throw stones!"

Leave the Druids. And stop breaking the balance, you need to be a supporter of conservatism, and besides, we won't change anything anyway, so there's no point in these conversations.
Druids, as true protectors of nature, should be in the castle, and they should also be a mage unit. Werewolves are already Necromancer-like, and we don't need undead. Ents are needed, riders on eagles :D :D :D :D :D :D :D :D :D Rider, what riders? And what kind of eagles are so big, or are the elves so small? And why do we need an analogue of a griffin?
