Add in zombie spawners and skeleton spawners. Also to stop people from earning masses of money lower the price of arrows, bows, bones, and rotten flesh. Skeletons don't give you iron/gold and zombies only drop iron, I doubt someone with no zombie spawner would even have iron anyway so please add them in Iv'e seen so many servers that are plain factions with them on but they're worth about $120,000 in game money and if these do lag out the server then make a cap of 2 or 3 spawners that you can buy
