Of course it isn't duping, silly goy! Just because a certain guild is known for duping, glitching, and hacking private servers doesn't mean they did it to this one! Just because a certain guild is known for getting buddy buddy with server admins and getting free items/loot/perks doesn't mean they did it on this one!
Stop paying attention to certain guilds my friend, stop paying attention to an economy already on the brink of being flushed down the toilet, and focus on the no mobs because they have "blizzlike" spawntimers and 3x the "blizzlike" server capactiy!
