I just played a Rome2 campaign, and even with radious or DEI, the mechanics and balance on the pikes you have in Attilas Ancient Empires, is way better. Not overpowered(enemy infantry still loses if they charge), but can be broken versus higher tier melee units. Makes it alot less tedious playing against Macedon etc.
Don't know if other players agree, but the balance is pretty nails on.
