I think this would work well in FFXIV. The main points I'd think would work well are special vendors in the cities sell different items depending on which areas you have under your control, supply quest (no teleporting allowed) to the Aetheryte while its under your control for a permanent discount (10%?) to all future teleports to that Aetheryte. Conquest points could maybe be made into GC Seals... but the rate at which you acquired them would have to be balanced at the same level as fates and only acquire them when you get exp from mobs... Then the winner could be determined from GC Seals gotten from killing mobs in the area and maybe also from fates.
