Today was my first time to wage war in C2C. Oh man, AI brought several stacks against my border city where largest was over 30 units! I was totally like "OH **** OH **** OH ****!" My city and I prevailed. Know why? AI didn't bring in any siege units! Archers used ranged attacks and many units charging the city had city raider promotion, but that's it. City got attacked by around 60 units or so in 2 turns, and there wasn't even single log ram. Is that intentional AI behaviour or what?
