I wish the Hunting Wolf was an actually recruitable unit.

The Steppe Hordes definitely used them.

And it would be cool to have a unit that only costs food but has a very long recruit time. To showcase the fact you have to train them. And since Wolves have the bonus vs Villagers damage, they would make a very scary raiding unit.

Imagine an early feudal Mongol Raid with Scouts and Hunting Wolves. You use the Scouts to distract any potential military unit while the Wolves are used to hunt down villagers with their bonus damage.
