It would be cool if barbarian camps evolved a bit along with their units, instead of always being a pre-historic campfire. And thus, they would no longer be barbarians forever, but something like this:
Ancient & Classical eras: barbarians
Medieval & Renaiscence eras: mercenaries
Industrial & Modern eras: luddites
Atomic & Information eras: terrorists
Just my 2 cents
