Yes I'm hoping for that as well. Shiny cosmetic armor, pets, mounts and titles all restricted by rating for the PvP elite.
I believe that PvP armor that affects performance should be the same for everyone. And you can't really upgrade anymore really with the diminishing returns we're getting.
War Hero to Battlemaster = 5% stat boost.
Elite War Hero to War Hero = 3% stat boost.
Whatever's Next to Elite War Hero = 1% stat boost?
At some points, PvP stats will plateau by the looks of things and skill will become the determining factor instead of gear.
That is where we get an expansion with increased level cap.
