A pvp server at which you can only raid during the weekends.
kinda like in pixark.
only then it's always the same as on pvp, only you can't damage the dinosaurs or buildings of other tribes during the weekdays.
Swamp fever and mage rabies are still a thing and can still be transmitted to make it harder to survive if you are in trouble.
in effect, if you have damaged a wall, foundation, ceiling, etc.
and it hasn't been fixed before the end of the week, it's still able to be broken if it is not connected to atleased connected to three other items.
so that the mass placing of pillars will be a whole lot harder and a lot more work.
also, it will make it easier to build up again after the weekend ends and you get a decent chance to strike back in a full-out attack when the workdays have passed.
I'd like to call these servers comeback-time-servers,
Though I wouldn't mind a different name.
