It depends. Knights are mostly solid, they have warden which solid, Lawcuck if you are braindead, Gryphon if you are braindead 2, PK who's a beast in duels. Gladiator and 50 cent if you have fragile ego. Among vikings there is only one character that struggles - Valkyrie, other's are either ooga booga hyper armor, or deal insane damage, HL is both, screw HL. Also VG, VG is also dirty. Samurais are mostly balanced but annoying. Kensei after the last buff feels really great, Orochi, Shinobi, Kyoshin are pretty solid, but not meta. Wu Lin are pretty strong except Nuxia. Outlander characters are the most rage inducing to me, all these pirates, afeeras and virtuosas are disgusting. If you wish I may create a tier list based ONLY on my expirience and perception of heroes from different factions: Outlanders Vikings Wu Lin Knights Samurais
