In the forums there is a discussion about the usefullness of taking scorpions onto the MP battlefield. I tried them in a friendly game with our tourney champion Scipio Africanus expecting to be blown away. To my surprise the scorpions had an extra purpose. They will take allmost a complete pila storm (they die off course). The inv battle after the pila exchange (6 vs 6 urban cohorts) was a piece of cake beacause my Urbans didn't loose quite as many soldiers as Scipio did.
