Lately in 1v1 I've been using walls to wall off a large section of the map. As you gain more land, build towers and buildings so you can gain control of it. Use the cats to take out the towers and barracks and have a large group of HHA's taking out the legions (by large i mean 60 or 70!) You don't need that many cats, just 10 or 20. Now if you're playing a Choson and you get a map with rivers then you can wall up the river banks and the hittite can make time to build up his HHA/cat force. The hittite won't have much of a chance to get going so he will be defeated quickly. On a wide open map with lots of space and no rivers, a fast choson will probably be all over a Hittite too fast. basically, its all ends up depending on map type. A bunch of people have gone over this topic at the DM forum.
