Additionally, Paladins and Shaman can finally be designed the way they were intended. "The core reason for us to share the Paladin and Shaman across the faction is so that we can differentiate them more. The way it stands right now, in the live game it's very difficult for us to do one thing with one class without doing something very similar to the other class. If the Paladin needs to get better tanking abilities then we need to do similar things with the Shaman. Or if we add more DPS to the Shaman we have to do similar things to the Paladin," Chilton says.
In other words, we're to fuking lazy and decided to rehash so old classes and call them new for each side. lame.
