A /staff command is a command which displays all staff on all servers when executed. This can be handy for new players as well as players who need assistance but are not sure who to ask (if you have a rank, you may have in-experienced people asking you whether you are staff or not). The /staff command is on the Jartex server which is most certainly one of GC's competitors. I would like this command implemented as it would be a step in the right direction for a cracked server like GC. I have attatched a picture from Jartex of the result of using the /staff command: yes i do occasionally play on other servers.
It's a very good idea but, a cheater/rule breaker can just check if there are staff members online and cheat when there aren't staff members online.
I see where you are coming from, but if the staff are on as much as they should be, then there won't be much time in the day when a staff member isn't online, and so it could potentially be a system used also to stop hackers when they see staff are online.
This probably won't be added just because there are a lot of staff on each server and positions are constantly changing. If you need to see the staff just ask on the GC discord.
