In this new world there is a mountain full of diamond and gold ore, and Im afraid it will not be the only one. Not only does this provide an off balance of resources in the game, it is also powerleveling many peoples mcmmo stats. This type of map is not suitable for a pvp survival world and should be replaced with a simpler map and/or have this type of mountain turned off in the config (all IMO of course). I'll let you all decide what would be the best way to deal with this.
