I know this is probably already suggested, but seeing as some areas such as around spawn are vastly depleted of resources, I have had an idea. Located outside carthage and in pvp are two enterances to a respurce world, which is in two tiers. The highest tier is the upper half of the resource world, reachable via the carthage shaft. This area will be sealed above and below by bedrock and will contain the basic ores (coal and iron). The lower tier will containall ores, acessible only via the pvp enterance. Pvp and grief will be allowed in these tiers. When I get home and have access to a pc I shall go further in depth.
