I've seen this idea on some other servers and thought it was an interesting idea. Leaderboards with stuff like the players with the most money, playtime, PvP score, etc. Just a little something to spice up competition. Unless something like that already exists, and I'm just blind.
For the PvP, we have /zc toppvp which shows the top 5 PvPers, for playtime you can check a website, but idk if that's possible to have a playtime leaderboard in game. Also about the money, there is this command which is /baltop, now I know it kinda lags the server, because it loads all the info of all players who've logged into ZC. It would be really cool though if there was a command only for like top 5 or top 10
