I played with the Turks and they can take Antioch and Constantinople from turn one. after that they can destroy the best Persian army at Mosul. next turn Trebizond and Canakkale will fall and remember that you said at the beginning good players should get weak factions

About Koj is because there are two different scripts for 1v1 war and 1v2 war .Koj is doing good until another enemy steps in . you can give them 10 stack if they are at war with 2 factions they still act in deference . these script are very obvious in diplomacy also.
