Well I have a idea when assaulting a heavily defended castle or village.
Why don't we try and find a way to impalement siege tower's and battering ram's also with catapult's
If we don't have these siege weapons then a castle or village it would be impossible to attack.
Also green skins need's a ORKAPULT it launches orks!!!!!!!!!!!!
