Interesting but it’s an incomplete picture.
1. Corrals use food as a resource input, which is slower to gather.
2. Corrals use of food to gather food also means that the food collection chart will have lots scarcity dips caused by capital investment costs. This is pretty dangerous and can bankrupt a player quickly.
3. Corrals require more micro.
4. Corrals require continual investment/management whereas ice houses just need to be built once.
5. Ice houses are unique to Persia, which has a higher pop cap/ eco potential, so more it’s easier to collect the input resources
6. You’re missing the corral training tech
7. Cows can be batch trained
8. You can build 7 (or more corrals) all at once
all in all, I agree ice houses need a buff but I don’t think it’s as desperate as the above portrays
Hero names were specifically removed from the AI names a while ago (https://gitea.wildfiregames.com/0ad/0ad/commit/22cbd39bbd46d1bf2e87b8c26ae58f28a6d6fa1e), so that's not an option, unfortunately.
