I think perhaps the biggest issue is just balancing ghost acres from land trading and bottom feeding. Perhaps if the ghost acre DR between the same two countries had a longer "memory". Thus, land trading would still be profitable, but not for the same two countries who hit each other (even just every other day).

One of my main concerns is that two players, in the same clan or opposing clans, can hit each other every day generating 4k+ ghosties per hit. Granted, they do have to rebuild the 6k acres which at large acres is about $900M but at their production levels, that would only take about 40 turns of income to produce.

Maybe that's not overpowered (which is why I wanted a discussion and not a suggestion, I'm really not settled on the matter), but if we think that it is, perhaps increasing ghost acre DR to 72 hours could help? This would also encourage a rotation of targets in bottomfeeding as the ghosties are a big portion of the gains.

In essence, this small change would not affect most people, continue to encourage land trading, but do so in a way that encourages spreading the hits. If alliances or players want to self farm, they can still do so, but with slightly more forethought required (and in alliance, it would require more people to be involved and more precision). Thoughts?
