RTW Vanilla, slingers are just another versions of peasants with a sling and don't have much use...

EB = Slingers from hell!!! They mow down heavily armoured units... Let us spare the one with large shields, if I was a Hastati, and I faced a lot of slingers, I will cover my face with my shield, rather than hit on the forehead like the foolish goliath... even with their shields, they can't do much if outflanked....
