My hope depends heavily on how much pvp content is implemented. I think the goof up with classes and jobs can be a benefit in this aspect where classes more then likely will out perform jobs in pvp content. Classes have more survivability and more flexibility as opposed to jobs, so the basis is already there. Keep jobs abilities focused on group/pve play and balance accordingly and give classes more pvp abilities and balance accordingly.

With that my folks we may have the holy grail where a game manages to balance pvp elements without destroying the pve aspect of the game
