1) Some sort of device or artifact that can link all the items in the account: Bank items, house items, backpack item and what is being worn, so we can easily find stuff that we might thought we lost.
So for say, you cannot remember where you left such an item, well if the whole account is indexed, you can search for such item and the system says, item is on X char in their bankbox or backpack or in the house chest X.
Call it the house cleaner, similar art can be used from the Bar keepers or stewards.
2) Mastery scroll book holder, same as he have for PS, SOTS AND SOAS, a book where we can put in the Masteries we get as storage
and maybe even use same system to upgrade them, so X of level 2s to make a Level 3. (This last part is optional, but for storage reason would be good if we did)
3) Account-bound, Mythical tokens, you can get 1 every 3 months, so players can make new character in new places.
4) Runic hammer/chistle/saw holders, similar art to the already one we got for normal stuff, but this one just for runics, as it should of been!
