Unfortunately, with the main stream use of Choson, this combination has become more popular than ever.  Choson gets it's strength through heavy amounts of Infantry and towering, the legion is their primary weapon.  Because both players will primarily be building  legions like crazy, a Greek player, or a smart Hittite player who builds Centurions, can easily shut down a Choson player.  If this combination is to be used effectively, Helepoli and Cataphracts (Yes, Cataphracts) may also be needed to fend off siege and especially opposing Helepoli and Centurions.  If a Greek gets built up, they can generally devastate Choson players severely.  Rushing is the only way to win these games, when dealing with equal skill levels.
