Mamluk, Knight, Druzhinik are all S tier cuz you can couch all the time. My ranking list for factions
Infantries: 1)Sturgia( thanks eb lol) 2)Vlandia 3)Battania 4)Empire 5)Aserai 6)Khuzait
Cavs: 1)Vlandia and Aserai 3)Sturgia 4)Khuzait 5)Empire 6)Battania
Archers: 1)Vlandia 2)Battania 3) Aserai 4)Khuzait and Empire 6)Sturgia
Edit: This list is made for good team vs good team (based on ratparty experience). On pub Khuzait and Empire dominate because or glaive and menavlion and because newbies can’t shoot
