Actually they will suffer less from arrow fend then Man troops, but it WILL help against Tien Chi anyway. At least they will have to engage you in close combat. They mostly rely on MAGIC and they have a lot of choices there. Also, they have troops with Glaive (10 damage, 4 range but attack and defense suffers) to tackle enemy mounted troops and cavalry of there own (heavy cavalry too). Of course if you lack air wizards Tien Chi archers and crosbows are gonna walk all over you.
