Currently, as soon as you put on a piece of gear it's permanently bound to you (to my knowledge) and cannot be given to other players. I suggest that, while I know selling gear isn't currently supported, that gear is added to the already present trading system between players in person, so you can look at each stat and how they compare to one another. Or, it could also be used from higher players to lower players in order to give them old gear rather than throwing it out or exchanging it for gold with the vendor, so it can still be put to some use. Solely suggesting for already worn gear that has been put out of use in favor of more powerful/higher stats!
