I had the idea that we scale the range of SOI for forts by size - What I mean is, the bigger the fort, the bigger the SOI. The reason for this is because at the moment there is no incentive to make large forts to reach your allies and rather just tiny 10-20 chunk forts with minimal effort and 0 risk of losing anything. We could also have a cap limit - for example the max limit to when size doesn't matter anymore for forts would be say 200 chunks, and making the fort any bigger than that would not give you additional SOI. This would also shape out SOI in interesting ways and I'm really curious how the map would look like and would also motivate players to make bigger and better forts as now there is a benefit of doing so.
