"Also I don't like /conn to be deleted. If the server would be FULL
then I would like it deleted, but now there's no lag from player
activity, so let them pvp in /conn if they like."
Thats yust the problem in my opinion.
If the server is not full, players should defenetly not be in Conn.
If there are enough players , maybe some can be in Conn.
But i rather see that they do training in their Guard systems.
