I’m surprised nobody else considers Berbers to be S-tier, their feudal play is fine, faster villagers helps out a lot in a ton of little ways, but the main one is making enemy M@A play way worse for getting returns on that investment.
Their feudal is good, helped by faster vills they farm well. They don’t blow you away in Feudal, but when they hit castle age the powerspike from cheap stable production can be lethal really easily. They’ve got the faster vills to help get you through the early ages cleanly and with less losses, and once Berbers are castle they have the initiative.
