A trading system at completion of activities. This is the only way I can see trading viable in this game without breaking it (and yes, it would break the game. With its limited number of different items, it would screw the whole system up). Make it to where there is a full blown party lobby after every activity (radical idea....lobbies in PvP activities) and allow the trading of the items that dropped from that activity ALONE. This way, its more in line with MMO drops that need to be dispersed among the party. Friend got 12 Ghorn, trade it to Friend #2 in the party that got etheric light from the same activity. Friend plays Raid with regular group and gets 3rd Fatebringer? At end of Raid, trade Fatebringer to Friend #5 in Raid that never got one for an epilogue or something that dropped for the guy. Now friends can help Friends without having the system exploited by players looking to make money off of people for their 20 Ghorns they've been saving for trading to make a quick buck.
