There seems to be no way to let bots communicate with each other like the way humans do by team chat. Actually in a 2v2 game, humans v. bots, humans can exchange info and tactics, bots can't - so chatting is cheating. Imagine sending "attack in 20 sec" to your bot ally to launch a synced attack. Or "need 2000 metal" to force a tribute. Mixed teams would add a new level to the game. Is it a big problem to put two way chat on the API? Sending is already there. Just listening is missing.
