With us coming up against the Garlean Empire I can see something like Campaign battles coming back. However since they have F.A.T.E.s in XIV it would be a lot more interesting. If they do this they could have specific FATEs at the key strategic points of each zone, the levels of the enemy would depend on previous wins/losses and other things we do that could undermine their support. They could have some that we initiate, some we have to wait and others we 'intercept' en route. This I would enjoy a lot.
