In A21, it depends on which biome you're in. In the desert, a horde on day 7 might be too much for cobblestone, and if you're in the winter biome or the wasteland, concrete is the absolute minimum. But for the pine forest, the point is true. I fought the day 7 horde in a cobblestone base and had hardly any damage.
