in each category there are a lot of assets for default Lobby players, and VIPs . What I suggest is that for example in the Lobby 1 of each mode could only access the vip ranges. Or for example one created separately. In the lobby they could only enter the staff and the iron ranges , lapis , gold , diamond , emerald and obsidian. This makes other players want to be surrounded by many VIPs , so that the range would be purchased :)
