While I would love the addition of at least one more free retainer or a private chest in the house/fc private room, being limited to 2 retainers has taught me to not be such a hoarder. I constantly look up items that I have to see if I might need them again in the future. If not, or if I might need it but could easily gather it myself quickly, I sell it. However, I do hope that SE does eventually give us more storage space soon.
