I really hope that you can add more reble units from outside the map.you can make mauryan empire reble invade taxila.You can certainly.make reble for kushan empire and han empire and the xiongnu.They all enter the map in this time frame.If you dont want to waste faction on them.Its fine.you can let them be rebel army and mercenary.Please do make units for those empires.It will add more variety to the game and make it more historical.many units in the game looks acturally the same.The diffenrence may be their weaponsIt will get bored if the units that cant change like the old eb1
