This company has been doing this since FFXI. You'd get a new event with new equipment and then it'd be months before you could store them away. Years, even, for some items. The excuse they gave back then is that they had the events and/or items coded into the game before they had the systems in place to accommodate the storage of them. What I'm saying is, it's not going away. I'm kind of hoping that the upcoming vanity system will come with extra storage to accommodate the extra items it will create but uh, yeah, not counting on it.
