I've been trying to go to a new expedition site every time, looking for Holy Sites, but I later realized (after re-visiting) the same place multiple times that it all of a sudden turned into a Holy Site.
Would it not be better that each Expedition site had a chance to generate as a Holy Site only upon first visit? And if it's not a holy site it's not a holy site?
This way I can just keep going back to the same place over and over again to grind out Holy Sites within or close to my realm which feels cheap and easy to cheese.
Instead of having to cut/hide stuff I think this could just be re-flavoured in-game.
