Seriously since the new DEI verion AI Carthage is probably the weakest faction in game. I usually play as Rome and I really liked the DEI Carthage, cos it was really a challenge to overcome their naval and land power. I started the game like 5 times now only to see Carthage destroyed in less then 50 turns by a combination of syrakousai/desert/spanish tribes. It's not that they're weak, it's just that AI is not even moving armies or recruiting. I see Cartrhaginian armies moving on map every 5 turns or something like that. It just looks like AI freezes for a few turns repeatedly.
