For now, the bank is serving passively to people's needs as when people check the bank, find something they want, they will ask for it.
However, if something is not in bank, they will not ask while still in need of that.
Maybe we shall encourage people to tell us what item or even active(lair/regional/NYR) they need so that we can make a better logistics system.
A good practice is http://omnedatumoptimum.red/forum/viewtopic.php?f=39&t=1547 (If we don't have that post, I guess most of museum item will just turned into shards XD)
However, people may be too shy to say what they want. Or consider the needs will be unlikely to fulfill, but the point is, at least we can know if an item is useful to others.
