I can also add argument to get this Special Courier Pass in shop. This will increase craft economy (still need to get weaponcraft/handcraft 500+ to get item to morph weapon to 65), and also increase number of ally activity for Dragon Lord Refuge / Tiamat Hideout.
But most important, this will increase (indirectly) number of player to join server : Lot of player are exhausted to gear up a new player but if they hear we will able to trade weapon dropped (by courrier pass or another way) , they will probably join us.
Or you can just like retail: add event with sweet droprate weaponbox and rollbackscroll in shop for this event.
