I keep seeing the war of the factions and other things in the game that make it seem like its better to choose warriors just from one faction. Is this at all true? Is there a benefit to only playing in 1 faction? I love all the Knights and would be happy to play them exclusively, but now there's the valkeyrie class which looks like the coolest one in the game. Would I miss out on splitting my time between these factions and exactly what do you get for the war of the factions?
