I don't know why they don't just make all these social quest reward items, and the vanity armor from the shop, bound to your account and made so you can reclaim them forever. There are items in the claim window like that already, that are infinitely claimable - so it's technically doable. That's 95% of the reason I stop myself from buying stuff - I don't have the room, and don't want to ditch power items to make space. But I would happily buy things if it went to my claims and I could delete them to make space for power items, but always have the option to get it back in the future, without paying time and time again.
