BungeeCord is very advanced yet it still doesn't have an up-to-date ranking system, some servers use plugins such as BungeeAdminTools and StaffChatBungee which both require permissions on BungeeCord, to do this you need to create a Staff Rank, add the user to the rank and restart the entire BungeeCord Proxy. I guess there are plugins such as BungeePerms but these are really buggy! An efficient permission system should we built into BungeeCord with commands such as: /gaddrank <RankName>,...
