Armament is expensive to maintain and support, and has to justify itself economically in the real world, not in batman comic adventures. Ruminants largely concentrated on outbreeding, or outrunning their predetors, or being too big and ugly to kill easily, and running efficiently on low-octane, easy to obtain fuels. Slow-breeding social predators are more of a boon than a threat to the ruminant gene-pool, so there's inadequaate genetic payback in getting into an arms race with them.
