What if, we give the faction that has the most territory after the alert has been stopped, a small prize besides ISO-4? Nothing major as a cosmetic but like a common/uncommon implant. (or a decal, idk) Now, stopping the faction is the major objective, ending with the most territory doesn't seem to bother me since 50 ISO-4 difference is really not much to care about, this would strengthen that urge to come out on top.
