@MojangSupport Y'know what I see Minecraft's copper lacking? Copper tools, copper armor, a copper cauldron for purifying water, and copper beacons.

Those are fun ideas! You can share your suggestions and feedback for Minecraft here: msft.it/6011iy7od. -AG

Wait, I got something else! Hear me out! WATER MINES! Crafted using a TNT block and 4 copper ingots. Will explode and destroy all underwater blocks upon touch. The number of chains added into the item via the crafting table will determine how high up the water mine will float.

That sounds cool, too! You should forward that idea to the suggestions and feedback site, as well! -AG

I would, if there was an actual direct PATH to actually SUGGEST an idea!
