This would be awesome! Gives identity and much more depth to the war. Now I know Classes in general haven't been revealed, though I hope when engaging another Faction, I would be fighting against another type of class. ie a Heavy Armor class could be a Warrior or an Armsmen or a Guardian depending on which Alliance your in. Or a caster type: Warlock / Wizard / Eldritch (Alliance specific.) Instead of just fighting the same Wizard just a different Race.
What do you think?
