I know Duping of any kind isn't allowed but I was surprised to find out that flower duping goes under that list for some reason. Dye is a huge factor in this server as it creates the many things we need that needs specific colored items such as wool and concrete. It's a real pain to get some of these dyes and the Auction House isn't that easy to access since most people aren't near any nation capitals, even considering the ones that aren't friendly. I don't see any reason not to reintroduce flower duping as that is the best way to fix some dye shortages overall. I know bonemeal on grass can give you flowers but that can only give a few at a time and don't guarantee the color you're looking for.
