Yeah trading in these sort of games is never good. It will be a headache for Bungie for one thing. Having played MMO's for years, one thing I've learned is how stupid people are and how easily they get conned when it comes to player trading. The number of times I've seem people crying on game forums because they have been scammed and expect the devs and mods to sort it out is crazy. Plus this place will just get flooded with even more crappy posts with people spamming "looking to trade" or "selling x,y and z" because we all know they won't stick to a dedicated trading sub forum, there is enough off topic shit in the main Destiny forum as it is.
