trading items with other players?

[LordOfTheGods]

wouldnt it be kinda need to add sorta like an auction house type of thing where players could sell the items they didnt wanna use anymore and other players could buy them, i think about it its like, say 4 example all the ppl who use purple items, after they get a better one what do they do sell it back 2 the black smith 4 not nearly as much as they bought it 4, when im sure there would be players out there who dont really have the means 2 buy a purple item but maybe could spend gold trading with other players, dont know how exactly it would all work, just had an idea and wanted to hear what everyone thought about it
