Wild wood rangers are under appreciated. They have a 2” reach on a small base!Used correctly, they do lots of damage because it is really easy to get all models in combat. A unit of 30 means a realistically achieved 61 attacks. I always take a block of 30. They lose effectiveness in smaller amounts; 10 is pointless.
Balance is critical in any AOS army and WWR are a great combat unit. They are compatible with wanderer tricks, so they are more versatile than allies. Alternatively, you could take an allied combat unit, but this potentially limits your game tactics. However, Thralls with a scyrer works really well.
And someone mentioned shooting out of combat for the nomad battalion volley thing. I disagree that it lets you ignore the combat restriction. That’s how I interpret it and play my games like that. I always err to the opponents advantage on vague rules.
