Come to think about it, slingers seem to be a liability early game. They're not good against anything. * Slingers are absolutely useless against horse spawns. Warriors on hills can hold off either. * Slingers aren't good vs anything in rough terrain * Slingers can't even protect you from attack anymore. Previously you could run warriors around while a slinger plinks them to death. Nowadays the AI will just focus down your city and slingers do nothing to stop this. You need warriors to prevent the city from going under siege. Even with archers it's hard. * Slingers also get crushed vs archers and chariots. Warriors lose to these but at least can hold ground. * Archers are good mind you, but if your rival is in forests or hills, they're not very good at attacking those cities. * Even scouts on good terrain are better for holding ground and they can help put a city under siege. * Warriors work with Oligarchy and upgrade to swords which are much more useful. So the only use in slingers is to upgrade to archers, in which case we save about 100 production for 120-160 gold. And archers cost gold to maintain. So, why build them at all beyond the few you want to become archers/boost machinery with? Also, that brings up my other question. Do warrior rushes work?
