Thanks for your reply madnessario as well as Dejan.This may be a special design as you say,but actually I can't agree with it.Because pila was designed as a throwing weapon,secondary for a spear.It looks strange to see legionnaires use such a short things to defend riders.If we think that legionnaires need a real spear or the damage of the pila is too much,I think giving a real spear to the soldiers or lower the damage may be better
