I know it's a pipe dream, but I'd love for all the various blue items to be storable. They're all untradeable, and all are significant thematically, whether they're artifacts of the primals, job-specific armor above and beyond artifact gear, or ancient allagan relics. Hell, even the ilvl 100-110 gear had a lodestone post giving lore about them being Gerolt's masterworks from before he became a drunk.
