I have checked this out in my area, as mentioned the hacking power bar alone limits land claiming. More importantly though, the way the mock system atleast in my phone works acts completely randomly and shifts around unpredictably within a fairly small region of about 3-5 square radius. There is no advantage at all because i cannot deliberately or precisely control where my location is. I could claim territory and build assets but it took literally days to do and if someone should attempt a raid i would need to rely on pure luck. Even if the spoofer managed to land on the raided area to block, i could not consecutively block multiple times predictably. For conducting raids its virtually impossible still since again i would need to rely purely on luck to land on an enemy territory, then i have to stay there for a pretty long while, in which the mock system simply cannot stay more than about 3-5 minutes at most as i have seen. Time of raids goes far beyond that and you will just be wasting hacking power vs actually going there. I also dont see the usefulness in battles, sure maybe you can fool wearable radar users and drones a bit, but there might be an in game perk for spoofing anyhow someday, either way it cannot defeat the line of sight of the inceptors.
Since it seems the point of the game will on battles more than harvesting i dont see how mocking will be useful or incentivized. I think it might actually be more of a general hinderance to progress and leveling up and is liable to helping the other side more.
