New units. Their discussion and selection of upgrades.

I always choose wild Ents because I'm always attacked by Light Elves. Ents use the "Wrath of the Forest" skill, increasing their initiative by 5. Then, this brutal monster with very high attack and an initiative of 12-13 (depending on the presence of artifacts) crushes everything in its path. The weakness in defense is neutralized by fairies. Considering all this, it's unclear why Ancient Ents are needed. Archers can be protected indirectly; it's not necessary to stand in front of them. The speed and initiative of the units allow this.
