That's what I've been saying. Spahbod, as far as I understand, is saying wall towers shouldn't be able to auto-shoot at all. I would be perfectly okay with not having them auto-shoot until a tech is researched (a revamped "Night's Watch" would work).But, IMHO, walls aren't just there to create "choke points." They're also usable to defend your entire "base" which is supposed to represent a (fortified) city. A city of the Hellenistic Age, an age where the sophistication of city fortifications grew by leaps and bounds. In fact, I would love to give the Hellenistic, Roman, and Carthaginian wall towers an extra upgrade that has them firing scorpion bolts. Assaulting a fortified location should be an extremely dangerous, bloody affair.
