I really wish there was a way for Admins to designate creations that are purely Admin-related, and for the rest of the players on a server. I wish the Admins could go in to our servers and do content-creation (shops/fighting pits/merchants/storyline) and then pop out and go back in as non-Admin to enjoy the game as a player.
At the moment I get told that xyz have just stolen all my abc from this or that chesr when it ain’t mine, but a loot chest. My game-placed NPCs don’t attack me when I am non Admin, but will attack everyone with me in the group.
If the game treated Admin created items/etc as owned by ADMIN_FLAG then it would be interesting to see - though, of course, Exploiters and Griefers would be all over this and servers will again be unplayable.
