Campaign has been greatly eclipsed by every other exp-gain possibility. As it is on Bismarck right now, San d'Oria is under attack (does not own any other territories), Bastok owns 4 areas outside of the city, and Windurst only owns 2. Dark Kindred territories haven't been touched since Allied Rings came out. I'd love skill-ups and perhaps other adjustments to this part of FFXI, too. Until getting the full Cobra Unit Harness set and the arrival of Abyssea, I loved Campaign despite its lacking further rewards (save for a tiny chance at a single piece of currency for relics). Now my medals are going away and my time is going into other activities instead.
... or did Campaign rewards increase?
