Id have too double check, but I probably going to try and spend less time on forums since it doesn't seem to be very productive. I guess you can always send me a PM, i usually get those notices. The earliest conversation I have from you is the spread convo from may 22nd, then "Spartans" May 27th followed by "want to help" June 3rd
Currently all civs should have. The main reason I brought it back was because then we can also make cav a little stronger and more useful, even for civs that don't have strong cavalry, they can protect a little with spikes. Since I'm having a hard time keeping track on forums and I guess understanding some of what you are saying, currently ChatGPT is my main source. It's said its plausible that all civs during the time would and could have built something similar to help deter cavalry.
