New units. Their discussion and selection of upgrades.

In my opinion, I prefer Nymphs. If there are many of them, they can overwhelm the enemy with a bee swarm attack, while Dryads can only resurrect themselves and an Ent once. (I like the bee swarm attack more). I prefer Death Dancers over Wind Dancers. They attack everyone around them – that's their strength. Secret Archers ignore defenses; they have a slight advantage, and they just destroy the enemy! Master Archers are also good; their arrow can stun, which is also dangerous. High Druids are better, in my opinion, because they have two Chaos spells and mana transfer and stone skin. But Elder Druids have channeling and stone skin, but I think High Druids are better. Battle Unicorns and Light Unicorns are equally strong, in my opinion, but I prefer magic resistance. Ancient Ents are better than Wild Ents. Wild Ents have Forest Wrath, which, in my opinion, deprives them of an important ability – entangling enemies with roots. Ancient Ents can root themselves, which is very good; it provides very strong defense. Crystal Dragons attack with a chain attack, which is somehow better than acid breath, but they removed the immunity. (I choose Crystal Dragons).
