I mean with their ability to expand quickly, scouts that choose upgrades, and free territory for their new cities, the Shoshone are completely overpowered. On top of that they get defensive bonuses in their own territory. They can snatch up land and immediately defend it. How does that make other expansionists civs like America and Russia look. At the beginning of the game, the most important time for growth, the Shoshone would take everything before any other civ could react. Give me one reason why they aren't in desperate need of a nerf.
