Presently, most players have storage toons that they have to log in and out of to find items that are being held by those toons. This is very time consuming and inaccurate, as I can never find everything I am trying to equip as it is somewhere among my 15 toons.
I would love to see shared banking expanded to more than double its current allotment (80 slots to 160 or 200+ slots) and make shared banking sortable. This would save me and everyone else a great deal of time and make finding appropriate gear much easier. I would even be willing to pay a monthly fee in Turbine Points for a large shared banking space with perhaps some other related banking perks such as more shared plat space.
