Bustr:
If one wants to furball GVs, one needs some degree of (localized) segregation for reasons stated earlier in this thread (see my first post).
However, I am not sure how best to do this. In some cases, it could perhaps be done quite easily. For example in Ndisles, all one would need is to do is preserve the TT island by making the 3 air bases uncapturable, thus retaining at least a foothold for each of the 3 countries. (Yes, I know it is theoretically possible to recapture the island remotely, but as mentioned in my first post it is difficult, it hasn't been happening, and the island is thus not available. At least if there were 2 countries left on it, one could switch to one of them).
(edit for spelling)
