There will always be issue with storage, its also unrealistic to just add primal weapons. If anything they should try making some furniture that you can store things in, a few mmos do this already...

Mannequin to store a single full gear set
Drawers/Wardrobes to store accessories and gear, 5 or so spaces
Racks to store weapons, also 5 or so spaces

Lets people store those glamors they want to save
Adds a bit more importance to housing, which comes and goes at times
And doesnt really diminish those away from buying retainers still, people will still be hasty, quick from a retain rather than taking the time to tp to house and such
