There are a lot of people that are complaining about "legacy" not being allowed to transfer yet. Legacy characters can affect the world in many ways. There are quite a few 1.0 characters that are maxed with all classes and have a lot of materials on them. Which some could and would use this to their advantage by controlling markets. Which in turn would influence the natural progression of the economy of a non legacy server. I believe as soon as they feel this to be a non issue they will allow legacy to move where they please.
