I don't know how I feel about this. Perhaps currently it would make sense if, theoretically speaking, Barca was a part of Terran since they're not self sufficient and would probably have an easier time defending the area if they could use our RCs. But once they are set up it will free up the Lowlands almost entirely allowing us to help expand into the north which, with Caerwyn falling, is very viable for us. A buffer around Shoka will allow for enormous growth in Shokalom, more than we would gain from holding Rettlewood.
More importantly, a weak or nonexistent Caerwyn will be less able to contain monster-spawns. Meaning that, as Caerwyn weakens, the pressure of monsters on our northern borders will increase. Thus, even to hold what we presently have, we will need a continually escalating supply of strength, which will have to come from our southern front and from new holdings in the north.
