I believe Nicknames should be disabled for regular players, it is very hard to find whose talking and can get very confusing at times.
There is a a command that lets you see what their real name is, (/realname [playername]) but it can be annoying to type each time you want to /kick, /tp or even ban.
I would kindly ask if Nicknames would be turned off.
Sincerely,
