Yes we do need that much. Consider the amount of characters there are that could use infusers, and consider that 14 infusers are available at maximum every 17 hours(+ kill time?) I would say that that number is just gonna drive prices down and give ALL a chance to get a hold of one, even if you dont happen to win loot rights.
Since when is too much good loot a bad thing? Lack of twinking/I am better than you?
