Which units would you replace in the Sylvan castle?

Everything about them should be delicate and graceful, just like their dragon. But what is this? If you paint it from brown to green, it will look like some kind of ogre. This toothy monstrosity has nothing to do with elven ents.

This spider-man... well, this tree-spider also has nothing to do with ents! It's as if the elves took an ordinary tree and carved this wonder out of it... they chopped off branches, bark, and everything else... nonsense, in my opinion.
In Warcraft, the ents are the best... and these are very far from them. In Heroes of Might and Magic III, they are 100 times better!

But as a creature, I like it. It's a tough little bastard. But visually, it's awful. Another minus for Ubisoft!
