Probably because they're hoping for ways to cockblock and MPK entire alliances out of the zone so they can hoard all the AF2 and currency.
That's unlikely to happen and there is no basis for it. The reason it's so unlikely to happen is partly because of the current number of people actually participating in Dynamis. If this were 6 years ago when dynamis was in it's heyday, there's a chance it might have been a problem. but it's not 6 years ago. It's today.
