Not much more to say about this since the title is self-explanatory but to me, it seems like people who are in the free world don't even bother going because it's boring for some and I myself don't have access to the free world yet but I think if I did I'd get pretty bored of it quickly, which is why it would be a good idea to add challenges maybe like:
-Kill 25 players in the free world
-Collect 1 player head
-Find a spawner
-Discover a Sea temple
-Discover a Village
-Kill 25 players in the free world
