They could easily do this and not have it be a bad thing for raiders. Very simple to do, just have the flagpole be the respawn point and if any enemy comes within the max radius that a lvl 10 base has it will not allow you to spawn just like it does in wasteland. I would love this cause i to hate having to be forced to build a base close to a spawn town just to be able to actually make it back to my base and not travel across the map.
