One solution for the implementation of BOP items would be:
- Player A is allowed to drop a BOP item in his/her legacy storage
- Player B in the same legacy is allowed to withdraw the item bound to Player A by paying a fee equal to the cost of the modifications (armoring/hilt/barrel, mod, enhancement and augment) in it. For the earpieces/implant/relics, the fee can be evaluated as the the cost of the extraction of the mods and enhancements of the same level of the item.
This way, people that want to send empty shells for the look pay nothing and, at the same time, people can't "cheese" the gearing grind more than how they do currently (i.e. emailing legacy bound gear)
