I think common drop items should be tradable. Things like weapons and armor dropped by regular monsters. It really makes no sense that such common items can't be traded. When farming for experience or materials and you end up with 30 staffs or bows, it would be nice to hand some off to newer players. It would also be an adorable way to help guild members. Inflation has gotten out of hand and this could help a little. Now I don't think everything should be made tradable. Items from mini bosses are up for discussion. But I'm all for keeping item drops from bosses as untradeable.
