I noticed the other day that I was sitting on a stack of something like 20 convenience items (Instant Repair Canisters, Boosters, Revive Orbs, etc). I don’t use them immediately because “I might need them later” and I don’t keep them in my inventory to use when I need them because “I might need them on an alt”. As such, the collect dust and occupy space in my bank.
I think it would be even more convenient if these types of items also were stored in a way that all characters on an account could use them instead of only the character with the item in their inventory.
