Hi itsthe noob again:D

Well I wouldn't say im a noob now because all your helped turned out tot work for me. My Roman Empire isnt in trouble, and the only people thats attacking me is the dog-gone Audis and the other barbarian faction that starts with an "A". But im not worried about them since their fairly weak, and the Audi are much stronger than I. But anyways are there any guides on best deployment formations? I checked all over and cant seem to find one. I need to know the best formation for a defense and the same for an offense
