Only the lead builders should get VIP, we don't know how much anybody getting VIP worked on the map.
Take for instance my map, since I'm a moderator I could have hypothetically given my 4 closest irl friends VIP on these servers even though I built it all by myself, with very minimal help from Team Elite.
Since we don't know how much work someone's put into a map, just have the lead builder get it.
Also, they should make either a Builder rank (Builder) and have them be able to kick Regular members, not Iron or above. Leave the VIP for, well, Very Important People. I don't think making a structure and placing some chests merits that description.
