So, We'll be adding a new feature that makes the regenerative ores wear out.
While it's wearing out, the ore will turn into cobblestone, instead of stone.
Send the following messege if a Player's attempting to break the cobblstone;
"&cThis Ore has worn out, it will heal soon" < Or something like that (You decide)
Please add sound effects! :)

Coal Ore = 4 blocks can be mined until it wears out.  // 1 minute and 20 seconds until it comes back.
Iron Ore = 4 blocks can be mined until it wears out. // 2 minutes until it comes back.
Gold Ore = 4 blocks can be mined until it wears out. // 2 minutes until it comes back.
Lapis Ore = 3 blocks can be mined until it wears out. // 3 mintes until it comes back.
Redstone = 3 blocks can be mined until it wears out. // 3 minutes and 10 seconds until it comes back.
Diamond Ore = 4 blocks can be mined until it wears out. // 4 minutes and 40 seconds until it comes back.
Emerald Ore = 5 blocks can be mined until it wears out. // 4 minutes and 50 seconds until it comes back.
Quartz Ore = 4 blocks can be mined until it wears out. // 6 minutes until it comes back.
Obsidian = 1 blocks can be mined until it wears out. // 8 minutes seconds until it comes back.

Here's a new command: (It'll be stressful)
Once you are teaming up with somebody, you cannot hit them.

/team invite (Player) - Invites the chosen Player to team up with you.
/team leave - Makes you leave the Team.
/team kick (Player) - Kick the chosen Player.
/team chat - Custom chat format that everybody else can't hear
