So I've been trying to figure this out. Right now I'm playing as Genoa and I've conquered most of Europe. I've made it to Greece and Egypt has expanded into Constantinople and the Balkans. We've naturally gone to war. My problems are with two units specifically; the Tabardiyya and Mamluk Horse Archers. The Tabardiyya destroy everything they get into contact with, have high morale and are armored, which would be manageable by shooting them, but the Mamluk Horse Archers have that covered. They seem to kill units very quickly and even outshoot my own crossbowmen. The horse archers I can recruit die easily and the Mamluks have good melee stats. It's still the mid 1300's, so the only gunpowder I have are handgunners and bombards. The worst part is that Egypt has hordes of armies, we're still even in terms of numbers however.
