Plus Sea of Thieves definitely has the “roaming group of dominators” issue. Server hopping looking for people/raids is pretty common there.
If they use the SoT system here is what is likely to happen: group server surfs to an easy/empty server, gets nuke codes. Surfs for a server where some group has built their own massive city. Uses the nuke codes they horded from the easy server to nuke the established group. Rinse and repeat.
It’s like in WoW when people server transferred with the shit to open AQ back in the day.
Now if you’re assigned a server from the moment you log in till the end of time? Well, that has a giant possibility of sucking ass forever. Maybe you want some hot PvP action, but no one else on your server does. So you kill them a few times and they just leave and never come back. Soon it’s just you and the mobs. Same goes the other way for the guys who just wanted some co-op Fallout with a few friends.
