I think it would be pretty cool if the next Minecraft version had IRON AND FLINT arrows. In the picture of arrows they look like they're metal. They could do more damage, and be shot farther. Also i think diamond swords should use iron as their hilt, because a little stick could break with a snap. I hope you like my suggestions!
