/bal

Something like this would take away from the simple survival that is the foundation of the server. There are plenty of servers with /bal, you should look for one of them if it's important to you. Simple is literally in the name. Diamonds aren't terrible hard to find. Dig in a straight line for a while and you'll find what you need. Don't like mining? Collect stuff players will pay you their diamonds for. Terracotta, sand, gravel, wood, wool, are all things people pay for these days. If that doesn't sound appealing you should find a creative server maybe. Good luck with your hunt, whatever you decide.
