If some how they made a real pvp key-blade war in the game it would be so one sided it would never work for any other teams but one. For Japan servers Unicornis would wipe the floor with sheer numbers. And the NA servers would get destroyed by the vast numbers of Vulpeus (witch is funny to think lore wise with her character). Its funny to think how no other union relay has a snow balls change in hell in beating them. While there is no bonus given to picking a union and its what ever one you like best it seems both servers have players choice these two over every one else (me included being a proud member of Vulpeus) All hail the King and Queen of the key-blade you mess with them your F>>>D.
