2 hours between cairns seems a little extreme, maybe instead of making it so you can't expand off fresh cairns, make it so they wont start gaining soak when next to a fresh cairn. That way if you expand a ton of cairns at once it would take a long time for them to set, but quick expansion would still be possible.
